Physics-based FET noise model applicable to millimeter-wave frequencies

A physics-based FET noise model applicable to MM-wave frequencies is presented. The noise model is based on the short-circuit noise current derived from a 2-D noise equi-potential surface analysis. The model requires only one fitting parameter and includes the feedback effect of C/sub gd/, so that it can be valid at frequencies close to f/sub max/. Good agreement with measurement was found up to 100 GHz.
