The efficient parallel implementation of a 3-D Monte Carlo device simulator is described. The parallel algorithm was implemented on a 64 node nCUBE multicomputer and its accuracy was validated by generating the static characteristics of a MESFET. Timing measurements were made to study the variation of the speedup of the parallel program as a function of the number of processors. We identify the...

Computer simulation of high-speed Gallium Arsenide Charge Coupled Devices is performed using an established twodimensional semiconductor device simulation program. The effect of active layer thickness on the Charge Transfer Efficiency (CTE) and the dynamic range is investigated using different active layers. Also, different gate architectures are compared for optimum dynamic range and compatibi...

We present novel RF switches using micro-electromechanical (MEM) technology. These MEM switches are built on GaAs substrates using GaAs MESFET MMICcompatible processes. The fabricated shunt switches showed an insertion loss of less than 0.2dB and an isolation of greater than 20dB up to 40GHz. The switching speed is 47μS. The broadband MEM switches are promising building blocks for wideband circ...

The paper presents the relative stability behavior of the GaAs MESFET under varied illumination and frequency. The model of the device is developed in MATLAB and explains the shifts in the pole positions of transfer function with illumination and frequency for the first time. The variations of minority carrier life time and signal to noise ratio various optical illuminations under different fre...

This paper describes an experimental GaAs MESFET static memory cell which overcomes the principal disadvantages of the conventional cell implementation. Cell size is 36x37 μm2 at 0.6 μm gate length. An experimental 32 word x 32bit array has been designed. From simulation results, an address access time of 1ns has been obtained. The cell can be operated at the single supply voltage from 1V to 2V...

Previously reported quasi-optical amplifier arrays have limited bandwidth and suffer from poor input/output isolation. These prsbllems can be solved by using traveling wave antennas and distributed amplifier techniques. FII'TD simulations of a linearly tapered slot array topology demonstrate very broadband quasioptical transitions are feasible with small unitcell aperture. Experiments using a s...
