Summary: Spice parameter lists from MOSIS

Spice model parameters are provided by MOSIS whenever they
send back a batch of fabricated integrated circuits to the
designers. (note: MOSIS is DARPA sponsored service which
interfaces between designers of integrated circuits and
various fabrication facilities) They do tests on the wafers
that the chips were located on to get the parameter values.
 One should be warned, however, that sometimes these
measurements are not too accurate and may even be way off
(this happened to me once). So one should look at the
parameter values closely - if they look reasonable then they
should be alright to use. 

If you want these typical spice parameters you may want to
e-mail a request to MOSIS (at mosis@isi.b.edu) or you can
e-mail myself and I will send you a few sets.
