It focuses on pulse amplitude modulation (PAM) set-up in order to minimize the inrush current peak. An overview of these machines and the control topologies that have been used with these machines are reported. The critical problem that happens when controlling a high-speed electrical motor is the high current peak in the start-up process, which will cause high power-losses. The main goal of this paper is to clarify how the inrush current peak can be minimized in the start-up process. PAM control method is proposed to use in the frequency inverter, simulation results for PAM & PWM control method, and steps to improve the PAM control are reported.

The converter is based on the LM2596 regulator and designed to step down the input voltage of +16.8V to +12V, +5V, and +3.3V output, which are suitable for the nanosatellite's various subsystems. The load switch is based on MOSFET and is used to turn on or off the power supply to a particular load and protect the nanosatellite from power surges. A prototype of a +12V DC/DC buck converter with a high side load switch has been realized and tested, which meets our requirements and shows a good efficiency of 89%. In addition, the prototype features a capacitor between the source and gate of the MOSFET, which has effectively reduced the inrush current, demonstrating the effectiveness of this approach in reducing surges of current when the load is connected. The output current and voltage were measured at 0.7A and 11.89V, respectively, making this design suitable for use in low-cost educational nanosatellites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DC%2FDC%20buck%20converter" title="DC/DC buck converter">DC/DC buck converter</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20switch" title=" load switch"> load switch</a>, <a href="https://publications.waset.org/abstracts/search?q=LM2596" title=" LM2596"> LM2596</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20power%20subsystems" title=" electrical power subsystems"> electrical power subsystems</a>, <a href="https://publications.waset.org/abstracts/search?q=nanosatellite" title=" nanosatellite"> nanosatellite</a>, <a href="https://publications.waset.org/abstracts/search?q=inrush%20current" title=" inrush current"> inrush current</a> </p> <a href="https://publications.waset.org/abstracts/166405/integration-of-a-load-switch-with-dcdc-buck-converter-for-power-distribution-in-low-cost-educational-nanosatellite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166405.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">101</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8975</span> Distance Protection Performance Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelsalam%20Omar">Abdelsalam Omar </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents simulation-based case study that indicate the need for accurate dynamic modeling of distance protection relay.

Gargava</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Energization of a transformer results in sudden flow of current which is an effect of core magnetization. This current will be dominated by the presence of second harmonic, which in turn is used to segregate fault and inrush current, thus guaranteeing proper operation of the relay. This additional security in the relay sometimes obstructs or delays differential protection in a specific scenario, when the 2<sup>nd</sup> harmonic content was present during a genuine fault. This kind of scenario can result in isolation of the transformer by Buchholz and pressure release valve (PRV) protection, which is acted when fault creates more damage in transformer. Such delays involve a huge impact on the insulation failure, and chances of repairing or rectifying fault of problem at site become very dismal. Sometimes this delay can cause fire in the transformer, and this situation becomes havoc for a sub-station. Such occurrences have been observed in field also when differential relay operation was delayed by 10-15 ms by second harmonic blocking in some specific conditions. These incidences have led to the need for an alternative solution to eradicate such unwarranted delay in operation in future. Modern numerical relay, called as intelligent electronic device (IED), is embedded with advanced protection features which permit higher flexibility and better provisions for tuning of protection logic and settings. Such flexibility in transformer protection IEDs, enables incorporation of alternative methods such as dynamic switching of second harmonic feature for blocking the differential protection with additional security. The analysis and precautionary measures carried out in this case, have been simulated and discussed in this paper to ensure that similar solutions can be adopted to inhibit analogous issues in future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=differential%20protection" title="differential protection">differential protection</a>, <a href="https://publications.waset.org/abstracts/search?q=intelligent%20electronic%20device%20%28IED%29" title=" intelligent electronic device (IED)"> intelligent electronic device (IED)</a>, <a href="https://publications.waset.org/abstracts/search?q=2nd%20harmonic%20inhibit" title=" 2nd harmonic inhibit"> 2nd harmonic inhibit</a>, <a href="https://publications.waset.org/abstracts/search?q=inrush%20inhibit" title=" inrush inhibit"> inrush inhibit</a> </p> <a href="https://publications.waset.org/abstracts/61864/transformer-life-enhancement-using-dynamic-switching-of-second-harmonic-feature-in-ieds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61864.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">299</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8972</span> Rotor Side Speed Control Methods Using MATLAB/Simulink for Wound Induction Motor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Kumar">Rajesh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Roopali%20Dogra"> Roopali Dogra</a>, <a href="https://publications.waset.org/abstracts/search?q=Puneet%20Aggarwal"> Puneet Aggarwal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent advancements in electric machine and drives, wound rotor motor is extensively used.

However, PV-hybrid-Dc-Ac Schemes using interface power electronic converters usually has negative impact on power quality and stabilization of modern electrical network under load excursions and network fault conditions in smart grid. Consequently, robust FACTS based interface schemes are required to ensure efficient energy utilization and stabilization of bus voltages as well as limiting switching/fault onrush current condition. FACTS devices are also used in smart grid-Battery Interface and Storage Schemes with PV-Battery Storage hybrid systems as an elegant alternative to renewable energy utilization with backup battery storage for electric utility energy and demand side management to provide needed energy and power capacity under heavy load conditions. The paper presents a robust interface PV-Li-Ion Battery Storage Interface Scheme for Distribution/Utilization Low Voltage Interface using FACTS stabilization enhancement and dynamic maximum PV power tracking controllers.

For proper use of convolution, the step response record length is required to be at least the same as the waveform duration to be evaluated. The current step generator based on the cable discharge is compared to the Blumlein generator. Moreover, the influence of each component of the system on the performance of the step is described, which allows building the appropriate measurement set-up.

Much attention has been focused on the output impedance of the Howland circuit. Here we focus on the maximum load of the Howland source and discuss the relationship between the circuit parameters at maximum load. We conclude that the signal input terminal of the feedback resistor should be as large as possible, but that the current-limiting resistor should be smaller. The op-amp saturation voltage should also be high. The bandwidth of the circuit is proportional to the bandwidth of the op-amp. The Howland current pump was simulated using multisim12. When the AD8066AR was selected as the op-amp, the maximum load was 11.5 kΩ, and the Howland current pump had a stable output ipp to 2mAp up to 200 kHz. However, with an OPA847 op-amp and a load of 6.3 kΩ, the output current was also stable, and the frequency was as high as 3 MHz. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-impedance" title="bio-impedance">bio-impedance</a>, <a href="https://publications.waset.org/abstracts/search?q=improved%20Howland%20current%20pump" title=" improved Howland current pump"> improved Howland current pump</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20characteristics" title=" load characteristics"> load characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=bioengineering" title=" bioengineering"> bioengineering</a> </p> <a href="https://publications.waset.org/abstracts/3294/load-characteristics-of-improved-howland-current-pump-for-bio-impedance-measurement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3294.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">513</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8965</span> Power Reduction of Hall-Effect Sensor by Pulse Width Modulation of Spinning-Current</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyungil%20Chae">Hyungil Chae</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work presents a method to reduce spinning current of a Hall-effect sensor for low-power magnetic sensor applications. Spinning current of a Hall-effect sensor changes the direction of bias current periodically and can separate signals from DC-offset. The bias current is proportional to the sensor sensitivity but also increases the power consumption. To achieve both high sensitivity and low power consumption, the bias current can be pulse-width modulated. When the bias current duration Tb is reduced by a factor of N compared to the spinning current period of Tₛ/2, the total power consumption can be saved by N times. N can be large as long as the Hall-effect sensor settles down within Tb. The proposed scheme is implemented and simulated in a 0.18um CMOS process, and the power saving factor is 9.6 when N is 10.

Turkey, as being one of the countries, which has liberalized its foreign trade in the 1980s, also needs to be studied in terms of the impact of liberalization on current account deficits. Therefore, the aim of this study is to find out whether trade liberalization has affected Turkey’s trade and current account balances. In order to determine this, yearly data of Turkey from 1980 to 2013 is used. As liberalization dummy, the year 1989, which was set for Turkey, is selected. Structural break test and model estimation results show that trade liberalization has a negative impact on trade balance but do not have a significant impact on the current account balance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=budget%20deficit" title="budget deficit">budget deficit</a>, <a href="https://publications.waset.org/abstracts/search?q=liberalization" title=" liberalization"> liberalization</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkish%20economy" title=" Turkish economy"> Turkish economy</a>, <a href="https://publications.waset.org/abstracts/search?q=current%20account" title=" current account"> current account</a> </p> <a href="https://publications.waset.org/abstracts/37704/the-impact-of-trade-liberalization-on-current-account-deficit-the-turkish-case" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37704.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">380</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8963</span> Harmonic Distortion Caused by Electric Bus Battery Charger in Alexandria Distribution System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Elhosieny%20Aly%20Ismail">Mohamed Elhosieny Aly Ismail</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper illustrates the total voltage and current harmonic distortion impact caused by fast-charging an electric bus and maintaining standard limit compliance.

The welding machine uses a power supply to create an electric arc between an electrode and the metal at the welding point. A current selector coil needed for current selection is connected to the primary winding. Electric power is supplied to the primary winding of its transformer and is transferred to the secondary winding by induction. The voltage and current output of the secondary winding are connected to the output terminal, which is used to carry out welding work. The output current of the machine ranges from 110amps for low current welding to 250amps for high current welding. The machine uses a step-down transformer configuration for stepping down the voltage in order to obtain a high current level for effective welding. The welder can adjust the output current within a certain range. This allows the welder to properly set the output current for the type of welding that is being performed. The constructed arc welding machine was tested by connecting the work piece to it. Since there was no shock or spark from the transformer’s laminated core and was successfully used to join metals, it confirmed and validated the design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AC%20current" title="AC current">AC current</a>, <a href="https://publications.waset.org/abstracts/search?q=arc%20welding%20machine" title=" arc welding machine"> arc welding machine</a>, <a href="https://publications.waset.org/abstracts/search?q=DC%20current" title=" DC current"> DC current</a>, <a href="https://publications.waset.org/abstracts/search?q=transformer" title=" transformer"> transformer</a>, <a href="https://publications.waset.org/abstracts/search?q=welds" title=" welds"> welds</a> </p> <a href="https://publications.waset.org/abstracts/125450/design-analysis-and-construction-of-a-250vac-8amps-arc-welding-machine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125450.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">181</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8961</span> Design of a Hand-Held, Clamp-on, Leakage Current Sensor for High Voltage Direct Current Insulators</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Morn%C3%A9%20Roman">Morné Roman</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20van%20Zyl"> Robert van Zyl</a>, <a href="https://publications.waset.org/abstracts/search?q=Nishanth%20Parus"> Nishanth Parus</a>, <a href="https://publications.waset.org/abstracts/search?q=Nishal%20Mahatho"> Nishal Mahatho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Leakage current monitoring for high voltage transmission line insulators is of interest as a performance indicator. Presently, to the best of our knowledge, there is no commercially available, clamp-on type, non-intrusive device for measuring leakage current on energised high voltage direct current (HVDC) transmission line insulators. The South African power utility, Eskom, is investigating the development of such a hand-held sensor for two important applications; first, for continuous real-time condition monitoring of HVDC line insulators and, second, for use by live line workers to determine if it is safe to work on energised insulators. In this paper, a DC leakage current sensor based on magnetic field sensing techniques is developed. The magnetic field sensor used in the prototype can also detect alternating current up to 5 MHz. The DC leakage current prototype detects the magnetic field associated with the current flowing on the surface of the insulator. Preliminary HVDC leakage current measurements are performed on glass insulators. The results show that the prototype can accurately measure leakage current in the specified current range of 1-200 mA. The influence of external fields from the HVDC line itself on the leakage current measurements is mitigated through a differential magnetometer sensing technique. Thus, the developed sensor can perform measurements on in-service HVDC insulators. The research contributes to the body of knowledge by providing a sensor to measure leakage current on energised HVDC insulators non-intrusively. This sensor can also be used by live line workers to inform them whether or not it is safe to perform maintenance on energized insulators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=direct%20current" title="direct current">direct current</a>, <a href="https://publications.waset.org/abstracts/search?q=insulator" title=" insulator"> insulator</a>, <a href="https://publications.waset.org/abstracts/search?q=leakage%20current" title=" leakage current"> leakage current</a>, <a href="https://publications.waset.org/abstracts/search?q=live%20line" title=" live line"> live line</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20field" title=" magnetic field"> magnetic field</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor" title=" sensor"> sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20lines" title=" transmission lines"> transmission lines</a> </p> <a href="https://publications.waset.org/abstracts/97695/design-of-a-hand-held-clamp-on-leakage-current-sensor-for-high-voltage-direct-current-insulators" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97695.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">173</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8960</span> Corrosion Evaluation of Zinc Coating Prepared by Two Types of Electric Currents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Sajjadnejad">M.

In direct and pulse current conditions, effect of maximum current was investigated on the coating properties. Also a comparison was made between the obtained coatings under direct and pulse current. Morphology of the coatings was investigated by scanning electron microscopy (SEM). Corrosion behavior of the coatings was investigated by potentiodynamic polarization test. In pulse current conditions, the effect of pulse frequency and duty cycle was also studied. The effect of these conditions and parameters were also investigated on morphology and corrosion behavior. All of DC plated coatings are showing a distinct passivation area in -1 to -0.4 V range. Pulsed current coatings possessed a higher corrosion resistance. The results showed that current density is the most important factor regarding the fabrication process. Furthermore, a rise in duty cycle deteriorated corrosion resistance of coatings. Pulsed plated coatings performed almost 10 times better than DC plated coatings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion" title="corrosion">corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=duty%20cycle" title=" duty cycle"> duty cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=pulsed%20current" title=" pulsed current"> pulsed current</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc" title=" zinc"> zinc</a> </p> <a href="https://publications.waset.org/abstracts/111558/corrosion-evaluation-of-zinc-coating-prepared-by-two-types-of-electric-currents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111558.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">122</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8959</span> Close Loop Controlled Current Nerve Locator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20A.%20Alzomor">H.

Locating peripheral nerves is preferred to be done using nerve stimulation. In order to generate a nerve impulse by electrical means, a minimum threshold stimulus of current “rheobase” must be applied to the nerve. The technique depends on stimulating muscular twitching at a close distance to the nerve without actually touching it. Success rate of this operation depends on the accuracy of current intensity pulses used for stimulation. In this paper, we will discuss a circuit and algorithm for closed loop control for the current, theoretical analysis and test results and compare them with previous techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Close%20Loop%20Control%20%28CLC%29" title="Close Loop Control (CLC)">Close Loop Control (CLC)</a>, <a href="https://publications.waset.org/abstracts/search?q=constant%20current" title=" constant current"> constant current</a>, <a href="https://publications.waset.org/abstracts/search?q=nerve%20locator" title=" nerve locator"> nerve locator</a>, <a href="https://publications.waset.org/abstracts/search?q=rheobase" title=" rheobase"> rheobase</a> </p> <a href="https://publications.waset.org/abstracts/2622/close-loop-controlled-current-nerve-locator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2622.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">253</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8958</span> PSRR Enhanced LDO Regulator Using Noise Sensing Circuit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Min-ju%20Kwon">Min-ju Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Chae-won%20Kim"> Chae-won Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeong-yun%20Seo"> Jeong-yun Seo</a>, <a href="https://publications.waset.org/abstracts/search?q=Hee-guk%20Chae"> Hee-guk Chae</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-seo%20Koo"> Yong-seo Koo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we presented the LDO (low-dropout) regulator which enhanced the PSRR by applying the constant current source generation technique through the BGR (Band Gap Reference) to form the noise sensing circuit.

However when the power system experiences an abnormal situation leading to huge current flow, then this huge current is proportionally injected to the protection and metering circuit. Since the protection and metering equipment’s are designed to withstand only certain amount of current with respect to time, these high currents pose a risk to man and equipment. Therefore during such instances, the CT saturation characteristics have a huge influence on the safety of both man and equipment and also on the reliability of the protection and metering system. This paper shows the effect of burden on the Accuracy Limiting factor/ Instrument security factor of current transformers and also the change in saturation characteristics of the CT’s. The response of the CT to varying levels of overcurrent at different connected burden will be captured using the data acquisition software LabVIEW. Analysis is done on the real time data gathered using LabVIEW. Variation of current transformer saturation characteristics with changes in burden will be discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accuracy%20limiting%20factor" title="accuracy limiting factor">accuracy limiting factor</a>, <a href="https://publications.waset.org/abstracts/search?q=burden" title=" burden"> burden</a>, <a href="https://publications.waset.org/abstracts/search?q=current%20transformer" title=" current transformer"> current transformer</a>, <a href="https://publications.waset.org/abstracts/search?q=instrument%20security%20factor" title=" instrument security factor"> instrument security factor</a>, <a href="https://publications.waset.org/abstracts/search?q=saturation%20characteristics" title=" saturation characteristics"> saturation characteristics</a> </p> <a href="https://publications.waset.org/abstracts/37462/analyzing-current-transformers-saturation-characteristics-for-different-connected-burden-using-labview-data-acquisition-tool" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37462.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">415</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8954</span> Characterization of the in 0.53 Ga 0.47 as n+nn+ Photodetectors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Zohra%20Mahi">Fatima Zohra Mahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Varani"> Luca Varani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present an analytical model for the calculation of the sensitivity, the spectral current noise and the detectivity for an optically illuminated In0.53Ga0.47As n+nn+ diode.
