Abstract :
An analytical model of GaAs MESFET output conductance with frequency- and temperature-dependent parameters has been developed. The accuracy of the model was tested by comparing the simulated results with actual data of devices with low pinch-off voltage. The results showed considerable improvement when compared with the simple Curtice model. It is concluded that since the simple analytical expressions are easily incorporated into standard MESFET circuit simulation programs such as SPICE, this model helps to overcome a major impediment to the design of precision GaAs analog and digital ICs.<>
