Direct use of a MESFET physical model, in nonlinear CAD

The authors present a CAD (computer-aided design) tool which combines a novel quasi-two-dimensional MESFET physical model with an efficient nonlinear circuit analysis technique. Device technological parameters (dimensions, doping profile, etc.) can be directly related to electrical performance with this tool, which can therefore be used in nonlinear circuit yield study and optimization. An excellent agreement between simulated and measured results was obtained. >
