Abstract :
A complete extraction method to define non-linear models for HEMT devices has been developped. The method is based on broadband small signal S-parameter and DC pulse measurements. Because of the self-consistent approach used for the parameter extraction, the complementarity of both measurement techniques is proved. A model has been validated up to 26 GHz for a 0.25 × 200 ¿m HEMT device for both hot and cold operating ranges and implemented into the LIBRA non-linear simulator.
