Abstract :
A new CAD oriented noise model of the GaAs small signal FET is proposed. It introduces only one parameter to describe noise properties of the MESFET, contrary to previous models, which used more numbers. Model components are bias and temperature dependent. Temperature dependence of parameters is modelled by a numerical approximation to the physical behavior of carrier mobility and carrier saturation velocity in GaAs. Comparison with measured and published transistor parameters is presented.<>
