Volterra series based nonlinear simulation of HBTsusing analytically extracted models

Abstract

An accurate HBT large signal model has been developed using an analytical equivalent circuit element extraction technique. Nonlinear characteristics are analysed by means of a Volterra series and agree with experiment. Nonlinear current cancellation effects can be analysed. Their presence also enhances convergence and the applicability of Volterra series to large-signal modelling.
