Abstract :
A bias-dependent model for MESFET and HFET devices under zero drain bias pinched-off conditions is proposed. Parasitic capacitances are evaluated from bias-dependent Y parameters over the whole frequency range. For the first time, it is possible to clearly distinguish between all intrinsic and extrinsic capacitances by considering the distributed nature of the device.
