The predecessor volume of this book was published in 1996. In the years
since then, some things have changed and some have not.
Two of the things that have not changed are the desire for better
models and faster simulations. I performed the original simulations on
my “hyperfast” 133-MHz computer! At the time, I thought if I could just
get a faster computer, all of our SPICE problems would be history, right?
Today I am simulating on a computer that has a 2.6-GHz processor with
512 MB of RAM, and I would still say that simulations run too slow.
The computer technology has evolved, but so have the models. In 1996
we were performing simulations on 100-kHz power converters, whereas
today I routinely see 1- and 2-MHz power converters.
