Abstract
In this paper, a simple technique for measuring and modeling the response of the gate-source and gate-drain diodes in a large-signal FET/HEMT model is presented. Measurements are conducted on an ATF36163 PHEMT transistor, and significant improvement in a large-signal model for the PHEMT is achieved by optimizing the response of the diode models. The significance of the gate-source and gate-drain diodes in large-signal modeling is discussed.
