Self-consistent parameter extraction for simulation models

An approach to deriving model parameters in which unique extraction algorithms are developed for each model form is described. Only after consistent extraction routines are developed for the model within a circuit simulator are then applied to the physical device. This provides an exact operational definition for each model parameter. Subsequent optimization, often considered unavoidable, can thus be reduced or eliminated. This approach is the basis of a SPICE model characterization system based on the Tekspice circuit simulator. Bipolar device measurement and Gummel-Poon extraction algorithms created with this system are demonstrated.<>
