Abstract
In this paper a semiempirical capacitance
model of GaAs FET, very useful for CAD of MMIC, is
proposed. The model fits the results of two dimensional
(2-D) simulations of device behaviour, accounting for the
most important microwave effects, by means of the
determination of an effective shape of the depletion
region in the active channel.
Simple physical equations and a few effective empirical
parameters, with a precise physical meaning, are
employed. So the initial estimation of parameters and
their extraction procedure result to be very easy.
In spite of its semiempirical nature the model does not
leave the control over physical and technological device
parameters to circuit designer, necessary to achieve a
reliable design.
The model usefulness and accuracy are experimentally
confirmed to be very satisfactory for different kinds of
MESFETs.
