An Approach to Extract Parameters for Statz MESFET Nonlinear Capacitor Model
You Liu · Microelectronics & Computer · 2000
An simple approach to extract the parameters of Statz GaAs MESFET nonlinear model is presented.The method is based on fitting measurement data with calculating data by point－ by－ point and then fitting all the points synthetically, and the parameters of capacitor models are determined correctly by using the data of small－ signal model distributed in the three areas of capacitance－ voltage characteristic curves as criterion. The calculating results show the method is still suitable for extracting parameters of Statz nonlinear capacitor model, under the condition that there are only a few data of capacitor Cgs and Cgd under different biases.
