Abstract
A general temperature dependent noise equivalent circuit parameter modeling procedure for MESFETs and PHEMTs is described. The noise source variations are fitted to linear functions of temperature over the 25 to 100/spl deg/C range. The originality of the contribution lies in the combined treatment of the temperature dependence of both the small signal model and the internal noise sources.<>
