Tm. Roh et al., A SIMPLE AND ACCURATE MESFET CHANNEL-CURRENT MODEL INCLUDING BIAS-DEPENDENT DISPERSION AND THERMAL PHENOMENA, IEEE transactions on microwave theory and techniques, 45(8), 1997, pp. 1252-1255
A new channel-current model of GaAs MESFET suitable for applications t
o microwave computer-aided design (CAD) has been developed. This model
includes the frequency-dispersion effects due to traps and thermal ef
fects. The model parameters are extracted from pulsed I-V measurements
at several ambient temperature and quiescent bias points. This model
is verified by simulating nonlinear circuits, such as a power amplifie
r and a mixer.
