Mc. Currasfrancos et al., DIRECT EXTRACTION OF NONLINEAR FET I-V FUNCTIONS FROM TIME-DOMAIN LARGE-SIGNAL MEASUREMENTS, Electronics Letters, 34(21), 1998, pp. 1993-1994
A simplified method for extracting two port nonlinear field effect tra
nsistor current sources from time domain microwave voltage and current
waveform measurements is presented. This method is based on the use o
f an appropriate reflective load-pull termination to ensure that the o
utput voltage is 180 degrees out of phase with the input voltage.
