Abstract
A modified GaAs MESFET-model has been developed to improve accuracy over a large bias range, particularly within the linear region. The enhancements consist of a modified Statz equation for the gate charge to improve the modeling of the gate drain capacitance, and an equation for the bias dependent drain source resistance for exact modeling of the dispersive output conductance.
