Abstract

This paper describes a scalable small-signal equivalent circuit for 0.25 μm gatelength Double Heterojunction δ-doped PHEMTs. The scaling rules for all elements except the pad capacitances and bondwire inductances have been determined. Good agreement is obtained between simulation results and measured results for 2 × 20μm 2 × 40μm 2 × 60μm 2 × 100μm gate width (nμumber of gate fingers × unit gate width) DH PHEMT.
