Non-Quasi-Static p-n Junction Model Without User-defined Recursion

Abstract

A model of the p–n junction that adequately describes the non-quasi-static effects of accumulation and relaxation of nonequilibrium charge carriers is considered. In this case, the diffusion charge equation is written in a closed form resolved with respect to the diffusion charge. This allowed computer programming of this model to be performed without user-defined recursion resolving the differential equation with respect to the diffusion charge. As a result, the non-quasi-static model of the p–n junction has been realized as an equivalent circuit containing only conventional quasi-static elements of computer-aided design systems.
