摘要：
A detail modeling of the d.c. small-signal parameters for AlGaAs/GaAs HEMTs and AlGaAs/InGaAs/GaAs Pseudomorphic HEMTs (PHEMTs) is presented. The theoretical calculations are based on self-consistent solution of Schrodinger and Poisson's equations. Study shows that pseudomorphic HEMTs have a higher transconductance and unity current gain cut-off frequency than those of normal AlGaAs/GaAs HEMTs. In this paper, the calculated transconductances are compared with experimental data and the results show excellent agreement for both devices.
