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 -- Steven V. Christensen U.C. College of Eng. schriste@uceng.uc.edu For the adventurous: svc@elf0.uucp

They give SPICE parameters for a "generic NPN" transistor which is the common 2N2222A device. -- -- Mark Johnson MIPS Computer Systems, 930 E.

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). -- --==---==---==-- Mimsy: Flimsy and miserable; another portmanteau word -- ARPA: cgs@umd5.UMD.EDU BITNET: cgs%umd5@umd2 -- -- UUCP: ..!uunet!umd5.umd.edu!cgs --

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! Christopher Johnson johnson@ge-dab.GE.COM
