Design of a Static Current Simulator Using Device Matrix Approach

Abstract

I-V characteristic is one of the important results produced by a device simulator. In this article, a novel and interactive matrix based algorithm is presented to draw the device structure in 2-D or 3-D style and to plot the I-V characteristic of the device for user specified doping and biasing conditions. Algorithm creates 2-D or 3-D matrix of the device from device description mentioned by the user. This device matrix undergoes many different operations, and various mathematical computations are performed, using which I-V characteristic is plotted. This approach gives a novel idea of basic device level tool development. The students and device level engineers can find this work useful which offers them an interactive and instant way to draw I-V characteristics of the device. The algorithm implementation is modular and matrix based, which is done using MATLAB®.
