Abstract :
This paper presents the use of harmonic amplitude and phase measurements in a new approach to nonlinear modeling of the frequency dispersive MESFET. Optimisation based nonlinear parameter estimation and a novel method for direct extraction of nonlinear dynamic drain characteristics are described Improved performance prediction using this new method is illustrated.<>
