Efficiency modeling for MHz DCDC converters at 40 V input voltage range [PDF]

open access: yesAdvances in Radio Science, 2014
Size and cost of a switched mode power supply can be reduced by increasing the switching frequency. This leads especially at a high input voltage to a decreasing efficiency caused by switching losses. Conventional calculations are not suitable to predict

Parasitic Effects on Electrical Bioimpedance Systems: Critical Review

open access: yesSensors, 2022
Parasitic capacitance represents the main error source in measurement systems based on electrical impedance spectroscopy. The capacitive nature of electrodes’ impedance in tetrapolar configuration can give origin to phase errors when electrodes are ...

Analysis and repair of timing deviation caused by filling dummy metal in advanced process chip

open access: yesDianzi Jishu Yingyong, 2022
In the finish stage of the chip physical design, in order to meet the metal density design rules, dummy metal fill needs to be added. The dummy metal fill generates external parasitic capacitances, which will deteriorate chip timing results.

Application of Perovskite Layer to Rotor for Enhanced Stator-Rotor Capacitance for PMSM Shaft Voltage Reduction

open access: yesEnergies, 2020
Adjustable speed drives use Pulse Width Modulation (PWM) to switch DC-bus voltage for the synthesis of three-phase voltages to provide power to the permanent magnet synchronous motor (PMSM).

Vertical MOSFETs for high performance, low cost CMOS [PDF]

open access: yes, 2007
-We present a review of recent reports on vertical MOSFETs which includes a summary of our own research in this area. Such devices can offer a decananometer channel length in a relaxed lithography. Furthermore, the footprint is substantially smaller than

Analysis of the Zero Overvoltage Switching Phenomenon

open access: yesIEEE Access, 2022
In common understanding, the fast switching speed of wide-bandgap devices leads to high overvoltage and oscillations, if no countermeasures are taken. Those countermeasures were introduced in the past, and include methods such as build-in gate resistors ...

Influence of parasitic capacitances in modeling and analysis of advanced floating gate memory devices [PDF]

open access: yes, 2009
In this paper, we report the impact of the parasitic capacitances in the modeling and analysis of advanced floating gate (FG) non-volatile memory (NVM) devices, especially on the coupling ratio.
