A complete extraction procedure able to determine MES-FET and HEMT nonlinea
r model parameters starting from standard de ann S-parameter measured data
is presented The procedure has been checked on different P-HEMTs, and avera
ge errors lower than 10% have been found for the static output characterist
ics and Sor S-parameters np to 50 GHz. (C) 1999 John Wiley & Sons, Inc.
