Abstract

We present a physics-based model for GaAs metal semiconductor field-effect transistors (MESFETs). The present model improves an existing model by allowing the possibility that the electric field near the source region can exceed a critical field, which is likely in an advanced submicrom MESFET operated in the quasi-saturation or saturation region. Furthermore, a realistic and nonuniform channel doping profile was considered in our calculations. Experimental data measured from a low-noise, ion-implanted MESFET are included in support of the model. The effects of different doping profiles and velocity profiles in the channel on the MESFET current-voltage characteristics were also investigated.
