Abstract
A method that permits a direct nonlinear extraction of two FET parameters, the drain current generator, and the gate source capacitor from large-signal waveform measurements, is presented. For demonstration, the high-frequency characteristics of the nonlinear drain current generator for a GaAs MESFET and a MODFET are extracted. Significant differences between the DC and RF characteristics, are observed and interpreted.<>
