Abstract
The conventional parasitic capacitance extraction always produces bias-dependent C/sub pd/, even though from the underlying physics, the parasitic capacitance is known to be bias-independent. In this paper, an improved model is thus proposed to evaluate the parasitic capacitances of a GaAs MESFET from the cold-FET S-parameters measurement. The resulting C/sub pd/ is found to be independent of V/sub gs/ when V/sub gs/\n\n\t\t
