COMPARISON BETWEEN NON-LINEAR MESFET MODELS : A CASE STUDY
There are several types of models exist for microwave MESFET equivalent circuit. These modeling techniques use different mathematical models to describe the same MESFET and give almost similar results. However, there are some differences in the outputs when compared to the experimental measurements....

| Résumé: | There are several types of models exist for microwave MESFET equivalent circuit. These modeling techniques use different mathematical models to describe the same MESFET and give almost similar results. However, there are some differences in the outputs when compared to the experimental measurements. In this paper, two of these dominanttheoretical modelsnamed as TAJIMA model and CURTICE model are applied to the sametypes of MESFETs that are selected in the measure of gate width and length. Comparisons are made withthe measured data sets. It is shown that TAJIMA model worked better on some particular types of the MESFETs because this model includes more parameters than that of CURTICE model, while the CURTICE modelworked better for some other types of MESFETs for different values of gate to source voltage. |
