Abstract :
A novel model method for III-V HEMTs small-signal model parameter extraction is presented in this work. All the model elements are directly derived from hot S-parameters, rather than cold S-parameters, by using vector fitting (VF) method The model renders excellent agreement with the measured and simulated data over 1 to 100 GHz, for a 2×150μm GaAs HEMT device manufactured in CETC-55 150nm GaAs pHEMT technology.
