Abstract
A method models the electrical characteristics of wide-channel transistors, such as power transistors, by generating a lumped-element distributed circuit model. More specifically, the active area of the transistor is organized in elementary transistor cells, which are substituted by active lumped elements. Similarly the passive area of the transistor is organized in elementary strip-lines, which are substituted by passive lumped elements. Preferably, the parameters of the lumped elements are extracted automatically from layout information, such as path dimensions, and technological data, such as sheet resistance of the metal layers, sheet resistance of the polysilicon layers and oxide thickness.
