Abstract
An alternative small signal equivalent circuit for MESFETs is proposed. An inductor is derived theoretically from the basic semiconductor equation. Instead of pure output conductance gds in conventional equivalent circuit models, output admittance Yds=Gds+jB is introduced. The delay time τ in the conventional models can be interpreted physically. Using the model, simulated S-parameters agree well with the measured ones in the frequency range from 1 GHz to 26 GHz
