Resumen
Descripción
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.
