Updated July 4,
here to go to our main page on computer-aided design
New for July 2009! And
we could surely use some help on this page... Spice is a general
purpose analog circuit simulator that is used to predict circuit
behavior. Spice is an acronym for simulation program for "integrated
circuits emphasis". Spice is to the time domain like linear
simulators are to the frequency domain, it can simulate voltage
transient behavior, but accuracy is best if you use it below microwave
frequencies. Thus in microwave circuits Spice is typically used
to simulate rise and fall times of modulator circuits, voltage regulator
noise rejection, etc.
History of Spice
Spice was originally developed
at the Electronics Research Laboratory of the University of California,
Berkeley in 1975.
PSpice is the PC version of Spice.
There are a zillion web sites
that will give you information on Spice, just google "spice
analysis" and you'll see.
This suggestion came from Fred.
QUCS is an open source digital
, RF and microwave circuit simulation program that may be of some
help to others in the RF field. Its full name is "Quite Universal
Circuit Simulator". The great thing is it is FREE and quite
powerful. Download it ...... and play with it......there are a
large selection of examples available. It has a nice GUI, user
friendly, and step by step tutorials. There are Linux, Mac and
Windows versions. It's available on sourceforge.
So are many other versions
