Automatic generation of RF compact models from device simulation

We review a recently proposed methodology for auto- matic generation of equivalent circuits from physical device simulation. The method is based on the calibration on a sim- plified equivalent-circuit model on simulation results, and can achieve an optimum balance of model complexity, ac- curacy, and generality. We discuss some of the possible ap- plications of the technique to the modeling of active devices, parasitic elements, and complex physical effects such as self- heating and hot-carrier transport.
