Abstract :
This paper introduces a new approach to the modeling of capacitance in FET devices, which we call division by current. It avoids the significant disadvantages of existing formulations, which we call division by capacitance and division by charge. The new method involves the use of a single nonlinear capacitance for the gate charge, and splitting the reactive gate current between the source and drain by a pair of nonlinear functions.
