Simulation results show that the circuit has a capacitive resolution of 8.06kHz/fF, which enables it for high resolution pressure detection.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Capacitance-to-frequency%20converter" title="Capacitance-to-frequency converter">Capacitance-to-frequency converter</a>, <a href="https://publications.waset.org/search?q=Capacitive%0D%0Apressure%20sensor" title=" Capacitive pressure sensor"> Capacitive pressure sensor</a>, <a href="https://publications.waset.org/search?q=Digital%20counter" title=" Digital counter"> Digital counter</a>, <a href="https://publications.waset.org/search?q=LC%20oscillator." title=" LC oscillator."> LC oscillator.</a> </p> <a href="https://publications.waset.org/16257/resonant-based-capacitive-pressure-sensor-read-out-oscillating-at-167-ghz-in-018" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/16257/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/16257/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/16257/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/16257/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/16257/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/16257/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/16257/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/16257/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/16257/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/16257/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/16257.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">2984</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Current Mode Logic Circuits for 10-bit 5GHz High Speed Digital to Analog Converter </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Zhenguo%20Vincent%20Chia">Zhenguo Vincent Chia</a>, <a href="https://publications.waset.org/search?q=Sheung%20Yan%20Simon%20Ng"> Sheung Yan Simon Ng</a>, <a href="https://publications.waset.org/search?q=Minkyu%20Je"> Minkyu Je</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>This paper presents CMOS Current Mode Logic (CML) circuits for a high speed Digital to Analog Converter (DAC) using standard CMOS 65nm process. The CML circuits have the propagation delay advantage over its conventional CMOS counterparts due to smaller output voltage swing and tunable bias current. The CML circuits proposed in this paper can achieve a maximum propagation delay of only 9.3ps, which can satisfy the stringent requirement for the 5 GHz high speed DAC application. Another advantage for CML circuits is its dynamic symmetry characteristic resulting in a reduction of an additional inverter. Simulation results show that the proposed CML circuits can operate from 1.08V to 1.3V with temperature ranging from -40 to +120°C.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Conventional" title="Conventional">Conventional</a>, <a href="https://publications.waset.org/search?q=Current%20Mode%20Logic" title=" Current Mode Logic"> Current Mode Logic</a>, <a href="https://publications.waset.org/search?q=DAC" title=" DAC"> DAC</a>, <a href="https://publications.waset.org/search?q=Decoder" title=" Decoder"> Decoder</a> </p> <a href="https://publications.waset.org/16693/current-mode-logic-circuits-for-10-bit-5ghz-high-speed-digital-to-analog-converter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/16693/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/16693/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/16693/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/16693/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/16693/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/16693/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/16693/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/16693/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/16693/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/16693/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/16693.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">5827</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> A Micro-Watt Second Order Filter for a Chopper Stabilized MEMS Pressure Sensor Interface</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Arup%20K.%20George">Arup K.

The circuit uses a single-ended folded-cascode operational amplifier and two GM-C filters connected in cascade. The circuit is realized in a 0.18 μm CMOS process and offers differential to single-ended conversion. The novelty of the scheme is the cascade of two GM-C filters to achieve a second-order filter while minimizing power dissipation. The simulated filter cutoff frequency is 1.14 kHz at common-mode voltage 1.65 V, operating from a 3.3 V supply while dissipating 172μW of power. The filter achieves an operating range of 1V for an output load of 1MOhm and 10pF. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Chopper%20Stabilization" title="Chopper Stabilization">Chopper Stabilization</a>, <a href="https://publications.waset.org/search?q=MEMS" title=" MEMS"> MEMS</a>, <a href="https://publications.waset.org/search?q=Pressure%20Sensors" title=" Pressure Sensors"> Pressure Sensors</a>, <a href="https://publications.waset.org/search?q=Low%20Pass%20Filter" title=" Low Pass Filter"> Low Pass Filter</a> </p> <a href="https://publications.waset.org/13840/a-micro-watt-second-order-filter-for-a-chopper-stabilized-mems-pressure-sensor-interface" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/13840/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/13840/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/13840/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/13840/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/13840/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/13840/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/13840/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/13840/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/13840/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/13840/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/13840.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">2104</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> An Energy Efficient Digital Baseband for Batteryless Remote Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Wei-Da%20Toh">Wei-Da Toh</a>, <a href="https://publications.waset.org/search?q=Yuan%20Gao"> Yuan Gao</a>, <a href="https://publications.waset.org/search?q=Minkyu%20Je"> Minkyu Je</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p class="Abstract" style="text-indent:10.2pt">In this paper, an energy efficient digital baseband circuit for piezoelectric (PE) harvester powered batteryless remote control system is presented. Pulse mode PE harvester, which provides short duration of energy, is adopted to replace conventional chemical battery in wireless remote controller. The transmitter digital baseband repeats the control command transmission once the digital circuit is initiated by the power-on-reset. A power efficient data frame format is proposed to maximize the transmission repetition time. By using the proposed frame format and receiver clock and data recovery method, the receiver baseband is able to decode the command even when the received data has 20% error.

In the earlier years, the researches mainly report linear energy harvesting techniques whereby interface circuitry is designed to have input impedance that match with the impedance of the piezoelectric transducer. In recent years non-linear techniques become more popular. The non-linear technique employs voltage waveform manipulation to boost the available-for-extraction energy at the time of energy transfer.  The fact that non-linear energy extraction provides larger available-for-extraction energy doesn’t mean the linear energy extraction is completely obsolete. In some scenarios, such as where initial power is not available, linear energy extraction is still preferred. A modified Buck Boost circuit which is capable of harvesting piezoelectric energy using both linear and non-linear techniques is reported in this paper. Efficiency of at least 64% can be achieved using this circuit. For linear extraction, the modified Buck Boost circuit is controlled using a fix frequency and duty cycle clock. A voltage sensor and a pulse generator are added as the controller for the non-linear extraction technique. </p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Buck%20boost" title="Buck boost">Buck boost</a>, <a href="https://publications.waset.org/search?q=energy%20harvester" title=" energy harvester"> energy harvester</a>, <a href="https://publications.waset.org/search?q=linear%20energy%20harvester" title=" linear energy harvester"> linear energy harvester</a>, <a href="https://publications.waset.org/search?q=non-linear%20energy%20harvester" title=" non-linear energy harvester"> non-linear energy harvester</a>, <a href="https://publications.waset.org/search?q=piezoelectric" title=" piezoelectric"> piezoelectric</a>, <a href="https://publications.waset.org/search?q=synchronized%20charge%20extraction." title=" synchronized charge extraction."> synchronized charge extraction.</a> </p> <a href="https://publications.waset.org/16656/modified-buck-boost-circuit-for-linear-and-non-linear-piezoelectric-energy-harvesting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/16656/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/16656/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/16656/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/16656/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/16656/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/16656/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/16656/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/16656/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/16656/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/16656/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/16656.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">2435</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Analog Front End Low Noise Amplifier in 0.18-µm CMOS for Ultrasound Imaging Applications </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Haridas%20Kuruveettil">Haridas Kuruveettil</a>, <a href="https://publications.waset.org/search?q=Dongning%20Zhao"> Dongning Zhao</a>, <a href="https://publications.waset.org/search?q=Cheong%20Jia%20Hao"> Cheong Jia Hao</a>, <a href="https://publications.waset.org/search?q=Minkyu%20Je"> Minkyu Je </a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>We present the design of Analog front end (AFE) low noise pre-amplifier implemented in a high voltage 0.18-<em>µ</em>m CMOS technology for  a three dimensional ultrasound  bio microscope (3D UBM) application. The fabricated chip has 4X16 pre-amplifiers implemented to interface   a 2-D array of    high frequency capacitive micro-machined ultrasound transducers (CMUT). Core AFE cell consists of a high-voltage pulser in the transmit path, and a low-noise transimpedance amplifier in the receive path. Proposed system offers a high image resolution by the use of high frequency CMUTs with associated high performance imaging electronics integrated together.  Performance requirements and the design methods of the high bandwidth transimpedance amplifier are described in the paper. A single cell of transimpedance (TIA) amplifier and the bias circuit occupies a silicon area of 250X380 <em>µ</em>m<sup>2</sup> and the full chip occupies a total silicon area of 10x6.8 mm².</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Ultrasound" title="Ultrasound">Ultrasound</a>, <a href="https://publications.waset.org/search?q=analog%20front%20end" title=" analog front end"> analog front end</a>, <a href="https://publications.waset.org/search?q=medical%20imaging" title=" medical imaging"> medical imaging</a>, <a href="https://publications.waset.org/search?q=beam%20forming" title=" beam forming"> beam forming</a>, <a href="https://publications.waset.org/search?q=biomicroscope" title=" biomicroscope"> biomicroscope</a>, <a href="https://publications.waset.org/search?q=transimpedance%20gain." title=" transimpedance gain.
