[sci.electronics] SPICE libraries/models wanted

schriste@uceng.UC.EDU (Steven V. Christensen) (10/15/90)

Hi,	
	I'm looking for an FTP site with various SPICE models, and
more importantly, libraries for various transistors. Specifically
I need the 2N3904, but I would like as many as I can get.


		Thanks,
		  Steven

Have a look at an article in Electronic Design magazine, April 13, 1989,
page 109.  They give SPICE parameters for a "generic NPN" transistor
which is the common 2N2222A device.

PSpice comes with a LOAD of device models, plus a program to help you
make up your own (by defining characteristics; it then comes up with
the necessary parameters). See if you can find someone who has it.
I don't think this comes in the student version,  which is free,
but rather the expensive commercial version.

The student version is not free (it is quite inexpensive, though).

There are two options:

1. Obtain the freeware copy of PSPICE from SIMTEL20. The freeware copy is
   copyrighted, so do not mistake it for public domain software. It calls
   itself a "Demo" version -- it works the same as PSPICE except it lacks
   magnetics (tranformers) and cannot analyze circuits with more than about
   100 nodes. It is more than sufficient for filter analysis, student
   projects, and the casual user.

2. By the book "SPICE: A Guide to Circuit Simulation & Analysis Using PSPICE"
   by Paul W. Tuinenga, MicroSim Corporation, published by Prentice-Hall,
   ISBN  0-13-834607-0

   The last page inside the back cover has order forms (with the P-H item
   numbers) for the "Student Version". Disks for the PC, PS/2, and MAC II
   are available for $7.00, $6.00, $6.00, respectively. (The PC version is
   on two disks, while the other two are on one disk a piece)

   I'm not sure what (if any) node limit exists in the Student version, but
   it does include magnetics (probably a few other things are included that
   are missing from the now somewhat dated "Demo" version).

Speaking of SPICE, a couple of years ago I remember seeing the FTP address
of a site which had the C source code for a version of SPICE (public domain).
Does anyone have that address?  Alternately, can anyone give me information
on obtaining this source code (other than going through Berkeley)?  This is
all with the understanding that it is the Public Domain version that I am
after.   Reply via e-mail.  Any help would be greatly appreciated.

Cheers!
