Abstract

A comprehensive charge control based analytical noise model for a symmetric tied gate 100nm gate-length In0.52Al0.48As/In0.53Ga0.47As DG-HEMT has been presented in this paper. The model evaluates the mean square drain noise current and gate noise current and the P, R & C noise coefficients for the device. The effect of the doping concentration and thickness of the donor-layer on the noise coefficients and hence on the overall noise performance of the device are also studied.
