An accurate CMOS interface small capacitance variation sensing circuit for capacitive sensor applications
(Springer Birkhauser, 2017-12)In this paper, an accurate front-end CMOS interface circuit for sensing very small capacitance changes in capacitive sensors is presented. The proposed structure scales capacitance variation to the sensible impedance ... -
Dual electrode capacitive micromachined ultrasonic transducer array for 1-D intracardiac echocardiography (ICE)
(American Society of Mechanical Engineers (ASME), 2007)We designed and fabricated a 64 element 1-D linear dual electrode Capacitive Micromachined Ultrasonic Transducer (CMUT) array operating at 9.5 MHz for Intracardiac Echocardiography (ICE). The dual electrode CMUT structure ... -
Forward-viewing CMUT arrays for medical Imaging
(IEEE-INST Electrical Electronics Engineers Inc, 2004-07)This paper reports the design and testing of forward-viewing annular arrays fabricated using capacitive micromachined ultrasonic transducer (CMUT) technology. Recent research studies have shown that CMUTs have broad frequency ... -
Integration of 2D CMUT arrays with front-end electronics for volumetric ultrasound imaging
(IEEE-INST Electrical Electronics Engineers Inc, 2008-02)For three-dimensional (3D) ultrasound imaging, connecting elements of a two-dimensional (2D) transducer array to the imaging system's front-end electronics is a challenge because of the large number of array elements and ... -
A low loss, low voltage and high Q active inductor with multi-regulated cascade stage for RF applications
(Institute of Electrical and Electronics Engineers Inc., 2015)Numerous structural planning of active inductors have been proposed as of not long ago in literature which showing tuning conceivable outcomes, low chip area and offering integration facility, they constitute promising ... -
A realistic quantum capacitance model for quantum Hall edge state based Fabry-Pérot interferometers
(Institute of Physics Publishing, 2017-01-25)In this work, the classical and the quantum capacitances are calculated for a Fabry-Pérot interferometer operating in the integer quantized Hall regime. We first consider a rotationally symmetric electrostatic confinement ... -
Single active device metamutator; Its application to impedance simulation and in particular to FDNR
(IEEE, 2017)he proposed Metamutator configuration employs only one Fully Differential Current Conveyor (FDCCII) which has 9 terminals including ground. By properly interconnecting these terminals a 4-port Metamutator is obtained without ...
