Device models for (M)MIC circuit design - benefits and limitations

An efficient and reliable device model library is the base for an accurate prediction of (monolithic) microwave integrated circuit ((M)MIC) performance and for computer aided circuit design in general. In this paper some trends in connection with microwave circuits are listed as well as the satisfaction of circuit designer with corresponding model libraries obtained by a survey is described. This will finally lead to an estimation of future demands in the area of CAD tool and model development
