Abstract :
The paper discusses a new large-signal MESFET model based on DC, S-parameter and nonlinear measurements. Physical constraints incorporated in the constitutive relations guarantee the model consistency in large-signal operation and improve the reliability of the parameter extraction process. Forward and reverse (breakdown) gate conduction effects are modeled from nonlinear data. Extensive comparisons with experimental results are presented.
