Abstract

The linkage between a physical device simulator for small- and large-signal characterization and CAD (computer-aided design) tools for both linear and nonlinear circuit analysis and design is considered. Efficient techniques for the physical DC and small-signal analysis of MESFETs are presented. The problem of physical simulation in a circuit environment is discussed, and it is shown how such a simulation makes possible small-signal models accounting for propagation and external parasitics. Efficient solutions for physical large-signal simulation, based on deriving large-signal equivalent circuits from small-signal analyses under different bias conditions, are proposed. The small- and large-signal characterizations allow physical simulation to be performed efficiently in a circuit environment. Examples and results are presented
