Abstract

A new parameter extraction methodology - local ratio evaluation is presented which is well suited for converting tone model to another. An example is given for VBIC model extraction by going through Spice Gummel-Poon (SGP) model. It is based on the fact that the VBIC model is a direct enhancement and extension of SGP model. Firstly, the standard SGP model is extracted in the standard way. Then, SGP model parameters are directly converted to VBIC model. Next, local modifications are carried out for those parameters that are affected by different equations used in the two models. Finally, new model parameters for enhanced modeling features are introduced by evaluating the difference between measurement and simulation.
