Adaptive EPFL-EKV long and short channel MOS device models for Qucs, SPICE and modelica circuit simulation

Equation-defined non-linear functional elements are important building blocks in the development of compact semiconductor device models. Current trends in compact device modeling suggest widespread acceptance among the modeling community of Verilog-A, for semiconductor device specification, model exchange and circuit simulation. This paper outlines techniques for the development of adaptive EPFL-EKV long and short channel MOS models which stress user selectable model features and diagnostic capabilities. Adaptive EPFL-EKV nMOS models based on Verilog-A and Modelica are introduced and their performance compared with simulation data obtained using the “Quite universal circuit simulator” (Qucs), SPICE and the Modelica simulation environment.
