The Switched Capacitor DAC mainly suffers from mismatch among capacitors. Mismatch among capacitors in DAC, causes non linearity between output and input. Dynamic Element Matching (DEM) technique is used to match the capacitors. According to element selection logic there are many types. In this paper, Data Weighted Averaging (DWA) technique is used for mismatch shaping. In this paper, the 4 bit DCT-SC-DAC with DWA-DEM technique is implemented using WINSPICE simulation software in 180nm CMOS technology.

Theoretically, it takes infinite time to fully charge or discharge a capacitor. The flow of charge is due to electrons having finite and fixed value of charge. If we carefully examine the charging and discharging process after several time constants, the points on q vs t graph become discrete and curve become discontinuous. Moreover for all practical purposes capacitor with charge (q0-e) can be taken as fully charged, as it introduces an error less than one part per million. Similar is the case for discharge of a capacitor, where the capacitor with the last electron (charge e) can be taken as fully discharged. With this, we can estimate the finite value of time for fully charging and discharging a capacitor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=charging" title="charging">charging</a>, <a href="https://publications.waset.org/abstracts/search?q=discharging" title=" discharging"> discharging</a>, <a href="https://publications.waset.org/abstracts/search?q=RC%20Circuit" title=" RC Circuit"> RC Circuit</a>, <a href="https://publications.waset.org/abstracts/search?q=capacitor" title=" capacitor"> capacitor</a> </p> <a href="https://publications.waset.org/abstracts/28590/behaviour-of-an-rc-circuit-near-extreme-point" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28590.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">443</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">1001</span> Innovative Three Wire Capacitor Circuit System for Efficiency and Comfort Improvement of Ceiling Fans</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20K.%20Saket">R.

Its low leakage/standby power property makes FinFETs a desirable option for memory sub-systems. Memory modules are widely used in most digital and computer systems. Leakage power is very important in memory cells since most memory applications access only one or very few memory rows at a given time. As technology scales down, the importance of leakage current and power analysis for memory design is increasing. In this paper, we discover an option for low power interconnect synthesis at the 32nm node and beyond, using Fin-type Field-Effect Transistors (FinFETs) which are a promising substitute for bulk CMOS at the considered gate lengths. We consider a mechanism for improving FinFETs efficiency, called variable supply voltage schemes. In this paper, we’ve illustrated the design and implementation of FinFET based 4x4 SRAM cell array by means of one bit 7T SRAM. FinFET based 7T SRAM has been designed and analysis have been carried out for leakage current, dynamic power and delay. For the validation of our design approach, the output of FinFET SRAM array have been compared with standard CMOS SRAM and significant improvements are obtained in proposed model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FinFET" title="FinFET">FinFET</a>, <a href="https://publications.waset.org/abstracts/search?q=7T%20SRAM%20cell" title=" 7T SRAM cell"> 7T SRAM cell</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=delay" title=" delay "> delay </a> </p> <a href="https://publications.waset.org/abstracts/16196/leakage-current-analysis-of-finfet-based-7t-sram-at-32nm-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16196.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">455</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">999</span> The Design of PFM Mode DC-DC Converter with DT-CMOS Switch</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jae-Chang%20Kwak">Jae-Chang Kwak</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> The high efficiency power management IC (PMIC) with switching device is presented in this paper.

The feature of consumption whivh has a very low power in designing pseudo-OTA is used to decreasing the total power consumption of the proposed CFOA. This design approach applies pseudo-OTA as input stage cascaded with buffer stage. Moreover, the DC input offset voltage and harmonic distortion (HD) of the proposed CFOA are very low values compared with the conventional CMOS CFOA due to symmetrical input stage. P-Spice simulation results using 0.18µm MIETEC CMOS process parameters using supply voltage of ±1.2V and 50μA biasing current. The P-Spice simulation shows excellent improvement of the proposed CFOA over existing CMOS CFOA. Some of these performance parameters, for example, are DC gain of 62. dB, open-loop gain-bandwidth product of 108 MHz, slew rate (SR+) of +71.2V/µS, THD of -63dB and DC consumption power (PC) of 2mW. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pseudo-OTA%20used%20CMOS%20CFOA" title="pseudo-OTA used CMOS CFOA">pseudo-OTA used CMOS CFOA</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20power%20CFOA" title=" low power CFOA"> low power CFOA</a>, <a href="https://publications.waset.org/abstracts/search?q=high-performance%20CFOA" title=" high-performance CFOA"> high-performance CFOA</a>, <a href="https://publications.waset.org/abstracts/search?q=novel%20CFOA" title=" novel CFOA"> novel CFOA</a> </p> <a href="https://publications.waset.org/abstracts/2597/design-of-cmos-cfoa-based-on-pseudo-operational-transconductance-amplifier" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2597.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">316</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">997</span> A High Linear and Low Power with 71dB 35.1MHz/4.38GHz Variable Gain Amplifier in 180nm CMOS Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sina%20Mahdavi">Sina Mahdavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Faeze%20Noruzpur"> Faeze Noruzpur</a>, <a href="https://publications.waset.org/abstracts/search?q=Aysuda%20Noruzpur"> Aysuda Noruzpur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes a high linear, low power and wideband Variable Gain Amplifier (VGA) with a direct current (DC) gain range of -10.2dB to 60.7dB.

It is noteworthy that the proposed idea can be able to apply on every differential amplifier, too.

During cochlear implant surgery, atraumatic electrode array insertion is considered to be a crucial step. However, during implantation, the mechanical behaviour of an electrode array inside the cochlea is not known. The behaviour of an electrode array inside of the cochlea is hardly identified by regular methods. In this study, a CI electrode array capacitive sensor system is proposed. It is able to automatically determine the array state as a result of the capacitance variations. Instead of applying sensors to the electrode array, the capacitance information from the electrodes will be gathered and analysed. Results reveal that this sensing method is capable of recognising different states when fed into a pre-shaped model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cochlear%20implant" title="cochlear implant">cochlear implant</a>, <a href="https://publications.waset.org/abstracts/search?q=electrode" title=" electrode"> electrode</a>, <a href="https://publications.waset.org/abstracts/search?q=hearing%20preservation" title=" hearing preservation"> hearing preservation</a>, <a href="https://publications.waset.org/abstracts/search?q=insertion%20force" title=" insertion force"> insertion force</a>, <a href="https://publications.waset.org/abstracts/search?q=capacitive%20sensing" title=" capacitive sensing"> capacitive sensing</a> </p> <a href="https://publications.waset.org/abstracts/80147/an-automated-sensor-system-for-cochlear-implants-electrode-array-insertion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80147.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">238</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">986</span> Improved Multilevel Inverter with Hybrid Power Selector and Solar Panel Cleaner in a Solar System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Oladoyinbo">S.

There are 3 main types of multilevel inverters (MLI); diode clamped, flying capacitor and cascaded MLI. A cascaded MLI requires the least number of components to achieve same number of voltage levels when compared to other types of MLI while the flying capacitor has the minimum harmonic distortion. However, maximizing the advantage of cascaded H-bridge MLI and flying capacitor MLI, an improved MLI can be achieved with fewer components and better performance. In this paper an improved MLI is presented by asymmetrically integrating a flying capacitor to a cascaded H-bridge MLI also integrating an auxiliary transformer to the main transformer to decrease the total harmonics distortion (THD) with increased number of output voltage levels. Furthermore, the system is incorporated with a hybrid time and climate based solar panel cleaner and power selector which intelligently manage the input of the MLI and clean the solar panel weekly ensuring the environmental factor effect on the panel is reduced to minimum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multilevel%20inverter" title="multilevel inverter">multilevel inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20harmonics%20distortion" title=" total harmonics distortion"> total harmonics distortion</a>, <a href="https://publications.waset.org/abstracts/search?q=cascaded%20h-bridge%20inverter" title=" cascaded h-bridge inverter"> cascaded h-bridge inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=flying%20capacitor" title=" flying capacitor"> flying capacitor</a> </p> <a href="https://publications.waset.org/abstracts/36730/improved-multilevel-inverter-with-hybrid-power-selector-and-solar-panel-cleaner-in-a-solar-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36730.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">366</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">985</span> Thinned Elliptical Cylindrical Antenna Array Synthesis Using Particle Swarm Optimization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Bera">Rajesh Bera</a>, <a href="https://publications.waset.org/abstracts/search?q=Durbadal%20Mandal"> Durbadal Mandal</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajib%20Kar"> Rajib Kar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sakti%20P.%20Ghoshal"> Sakti P.

The Particle Swarm Optimization (PSO) method, which represents a new approach for optimization problems in electromagnetic, is used in the optimization process. The PSO is used to determine the optimal set of ‘ON-OFF’ elements that provides a radiation pattern with maximum SLL reduction. Optimization is done without prefixing the value of First Null Beam Width (FNBW). The variation of SLL with element spacing of thinned array is also reported. Simulation results show that the number of array elements can be reduced by more than 50% of the total number of elements in the array with a simultaneous reduction in SLL to less than -27dB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thinned%20array" title="thinned array">thinned array</a>, <a href="https://publications.waset.org/abstracts/search?q=Particle%20Swarm%20Optimization" title=" Particle Swarm Optimization"> Particle Swarm Optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=Elliptical%20Cylindrical%20Array" title=" Elliptical Cylindrical Array"> Elliptical Cylindrical Array</a>, <a href="https://publications.waset.org/abstracts/search?q=Side%20Lobe%20Label." title=" Side Lobe Label."> Side Lobe Label.</a> </p> <a href="https://publications.waset.org/abstracts/4068/thinned-elliptical-cylindrical-antenna-array-synthesis-using-particle-swarm-optimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4068.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">443</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">984</span> High Precision 65nm CMOS Rectifier for Energy Harvesting using Threshold Voltage Minimization in Telemedicine Embedded System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hafez%20Fouad">Hafez Fouad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Telemedicine applications have very low voltage which required High Precision Rectifier Design with high Sensitivity to operate at minimum input Voltage.

Moreover, the performance of the wireless transceivers rigorously depends on the performance of its first block T/R switch. This article proposes a design of a high performance T/R switch for 2.4 GHz RF wireless transceivers in 0.13 µm CMOS technology. The switch exhibits 1- dB insertion loss, 37.2-dB isolation in transmit mode and 1.4-dB insertion loss, 25.6-dB isolation in receive mode. The switch has a power handling capacity (P1dB) of 30.9-dBm. Besides, by avoiding bulky inductors and capacitors, the size of the switch is drastically reduced and it occupies only (0.00296) mm2 which is the lowest ever reported in this frequency band. Therefore, simplicity and low chip area of the circuit will trim down the cost of fabrication as well as the whole transceiver. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CMOS" title="CMOS">CMOS</a>, <a href="https://publications.waset.org/abstracts/search?q=ISM%20band" title=" ISM band"> ISM band</a>, <a href="https://publications.waset.org/abstracts/search?q=SPDT" title=" SPDT"> SPDT</a>, <a href="https://publications.waset.org/abstracts/search?q=t%2Fr%20switch" title=" t/r switch"> t/r switch</a>, <a href="https://publications.waset.org/abstracts/search?q=transceiver" title=" transceiver"> transceiver</a> </p> <a href="https://publications.waset.org/abstracts/28930/design-of-a-high-performance-tr-switch-for-24-ghz-rf-wireless-transceiver-in-013-m-cmos-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28930.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">448</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">982</span> Electrolytic Capacitor-Less Transformer-Less AC-DC LED Driver with Current Ripple Canceller</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasunori%20Kobori">Yasunori Kobori</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Quan"> Li Quan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shu%20Wu"> Shu Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Nizam%20Mohyar"> Nizam Mohyar</a>, <a href="https://publications.waset.org/abstracts/search?q=Zachary%20Nosker"> Zachary Nosker</a>, <a href="https://publications.waset.org/abstracts/search?q=Nobukazu%20Tsukiji"> Nobukazu Tsukiji</a>, <a href="https://publications.waset.org/abstracts/search?q=Nobukazu%20Takai"> Nobukazu Takai</a>, <a href="https://publications.waset.org/abstracts/search?q=Haruo%20Kobayashi"> Haruo Kobayashi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes an electrolytic capacitor-less transformer-less AC-DC LED driver with a current ripple canceller.

The receiver front-end comprises a wideband low-noise amplifier (LNA), and a double-balanced Gilbert cell mixer with a current-reused RF single-to-differential (STD) converter, an LO Marchand balun and a baseband amplifier. The receiver front-end consumes 34.4 mW and achieves LO-RF isolation of 60.7 dB, LO-IF isolation of 45.3 dB and RF-IF isolation of 41.9 dB at RF of 60 GHz and LO of 59.9 GHz. At IF of 0.1 GHz, the receiver front-end achieves maximum conversion gain (CG) of 26.1 dB at RF of 64 GHz and CG of 25.2 dB at RF of 60 GHz. The corresponding 3-dB bandwidth of RF is 7.3 GHz (58.4 GHz to 65.7 GHz). The measured minimum noise figure was 5.6 dB at 64 GHz, one of the best results ever reported for a 60 GHz CMOS receiver front-end. In addition, the measured input 1-dB compression point and input third-order inter-modulation point are -33.1 dBm and -23.3 dBm, respectively, at 60 GHz.

The peak gain of the antenna is 3.4 dB at 5.9 GHz, which makes it suitable for vehicular communication. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antenna" title="antenna">antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=array" title=" array"> array</a>, <a href="https://publications.waset.org/abstracts/search?q=reconfigurable" title=" reconfigurable"> reconfigurable</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicular" title=" vehicular"> vehicular</a> </p> <a href="https://publications.waset.org/abstracts/85090/pin-diode-based-slotted-reconfigurable-multiband-antenna-array-for-vehicular-communication" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85090.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">256</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">976</span> Hybrid Antenna Array with the Bowtie Elements for Super-Resolution and 3D Scanning Radars</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Somayeh%20Komeylian">Somayeh Komeylian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The antenna arrays for the entire 3D spherical coverage have been developed for their potential use in variety of applications such as radars and body-worn devices of the body area networks. In this study, we have rigorously revamped the hybrid antenna array using the optimum geometry of bowtie elements for achieving a significant improvement in the angular discrimination capability as well as in separating two adjacent targets. In this scenario, we have analogously investigated the effectiveness of increasing the virtual array length in fostering and enhancing the directivity and angular resolution in the 10 GHz frequency. The simulation results have extensively verified that the proposed antenna array represents a drastic enhancement in terms of size, directivity, side lobe level (SLL) and, especially resolution compared with the other available geometries. We have also verified that the maximum directivities of the proposed hybrid antenna array represent the robustness to the all  variations, which is accompanied by the uniform 3D scanning characteristic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bowtie%20antenna" title="bowtie antenna">bowtie antenna</a>, <a
