Indeed Larry and Berkley are correct!
Unfortunately I only looked at a few lines of code around
the calculation of the above FACTOR. I never considered
the possibility that COX was the Gate Capacitance(Cox*W*L)(F)
rather than the Oxide Capacitance(Cox)(F/m**2). I could go on
about this being a poor choice for a variable name when
it *traditionally* means something different, but I won't.
After all, we can only use 6 character names in standard fortran
and I'm sure spice must use most of the 1.5e9 available.(:-)
