A new large signal model for HEMT's and MESFET's, capable of modeling the current-voltage characteristic and its derivatives, including the characteristic transconductance peak, gate-source and gate-drain capacitances is described. Model parameter extraction is straightforward and is demonstrated for different submicron gate-length HEMT devices including different delta-doped pseudomorphic HEMTs on MESFET. Measured and modeled dc and S-parameters are compared and found to coincide well.
