In this paper a modified, simple and accurate explicit expression of dc I-V characteristics of GaAs MESFETs is presented. The model proposed here allows to obtain the best fit with measured I-V device characteristics, especially in the knee region in which other models are less accurate. Comparison with other dc models of MESFETs indicates the new model as the most accurate one. The model can be easily implemented in programs of computer-aided nonlinear analysis and design of circuits with GaAs MESFETs

Abstract
In this paper a modified, simple and accurate explicit expression of dc I-V characteristics of GaAs MESFETs is presented. The model proposed here allows to obtain the best fit with measured I-V device characteristics, especially in the knee region in which other models are less accurate. Comparison with other dc models of MESFETs indicates the new model as the most accurate one. The model can be easily implemented in programs of computer-aided nonlinear analysis and design of circuits with GaAs MESFETsFile in questo prodotto:
