Abstract

In this paper a novel analytical approximation method for surface potential (@j"s) calculation in compact MOSFET model is presented. It achieves excellent accuracy and good calculation speed over all regions from accumulation to strong inversion. With this approximation method, a surface potential-based compact model for short channel MOSFET is developed. Comparison with measured data is also presented to validate the new model.
