A new empirical nonlinear model for HEMT-devices
Paper i proceeding, 1992
A novel signal model for HEMTs (high-electron-mobility transistors) capable of modeling the current-voltage characteristic and its derivatives, including the characteristic transconductance peak and gate-source and gate-drain capacitances, is described. Model parameter extraction is straightforward and is performed for a submicron gate-length ∂-doped pseudomorphic HEMT. The model has been used to predict the DC- and S-parameters of the devices and different nonlinear circuits such as mixers and multipliers with very high accuracy.
