A numerical optimization procedure to obtain SPICE MOSFET model level 1 parameters from model level 49
Description
We propose in this paper a procedure to obtain SPICE MOSFET Model Level 1 parameters from SPICE MOSFET Model Level 49. Our proposed method follows a general curve fitting strategy using numerical optimization to extract the SPICE level 1 parameters from the characteristic curves of the corresponding MOSFET using SPICE level 49 model. The optimization procedure is described, including the definition of the objective function. We also review a classical method widely used for SPICE Model Level 1 parameter extraction based on linear regression. A comparison of the two methods is realized in terms of accuracy of the resultant models. Our proposed method for parameter extraction proves to be more accurate.ITESO, A.C.
