This paper is a continuation of [9], where we analyzed steady-states of the nonlinear parabolic problem ut = ∆u− λf(x) (1+u)2 on a bounded domain Ω of R with Dirichlet boundary conditions. This equation models a simple electrostatic Micro-Electromechanical System (MEMS) device consisting of a thin dielectric elastic membrane with boundary supported at 0 above a rigid ground plate located at −1....

We analyze the nonlinear elliptic problem ∆u = λf(x) (1+u)2 on a bounded domain Ω of R with Dirichlet boundary conditions. This equation models a simple electrostatic Micro-Electromechanical System (MEMS) device consisting of a thin dielectric elastic membrane with boundary supported at 0 above a rigid ground plate located at −1. When a voltage –represented here by λ– is applied, the membrane d...

in this paper, computer simulation of a three-phase synchronous motor drive is described. this drive/system is supplied with a new type of pulse-width modulated voltage source inverter (pwm vsi) whose amplitude of the first harmonic, compared to a conventional sinusoidal pwm vsi, is increased by about 17% and whose amplitude of higher harmonics is also reduced inversely proportional to their or...

This work studies the effects of dynamic threshold design techniques on the speed and power of digital circuits. A new dynamic threshold transistor structure has been proposed to improve performances of digital circuits. The proposed switched-capacitor dynamic threshold PMOS (SC-DTPMOS) scheme employs a capacitor along with an NMOS switch in order to effectively reduce the threshold voltage of ...

A previously proposed two-terminal carbon-nanotube-based device with closed-loop feedback is demonstrated through in situ scanning electron microscopy (SEM) experiments. The pull-in/pull-out tests were carried out using a multi-walled carbon nanotube (MWCNT) welded to a conductive probe attached to a nanomanipulator. The MWCNTs were cantilevered over a gold electrode and electrostatically actua...

As the aspect ratio of the devices shrinks down, the power supply voltage should be reduced to meet low power requirements, and the threshold voltage should also be reduced to achieve high performance. This, however, leads to exponential increase in leakage current; hence the circuit’s reliability is also affected. A new domino circuit is proposed with reduced power and lower leakage for wide f...

Abstract — In CMOS circuit’s design, as the threshold voltage is reduced due to voltage scaling, it leads to increase in sub-threshold leakage current and hence static power dissipation. In this paper we propose a power reduction technique named transistor gating. In this technique two sleep transistors PMOS and NMOS are inserted in between the supply voltage and ground. A PMOS is inserted in b...
