LTspice for Theremin circuits

FredM

LTspice is available free from http://www.linear.com/

This simulator is superb, and suitable for all designers, from beginners to 'advanced'.. It is well suited to simulation of Theremin circuits.

 

The best tutorial I have found to get you started can be downloaded at

 

This zip file contains a PowerPoint presentation SWCAD.PPT  and running this teaches you all the basics you need start using LTspice.

 

The Full reference manual is here: http://ltspice.linear.com/software/scad3.pdf

A few good guides:

http://web.cecs.pdx.edu/~ssuzuki/engr_notes/ltspice/LTSpice_help.pdf (A good tutorial, particularly on setting up simulation types and creating subcircuits.)

http://pages.suddenlink.net/wa5bdu/ltguide.pdf  (useful tutorial - data on transformers..)

http://home.mindspring.com/~eeweb/ltspicesubckts.pdf (more advanced sub-circuits)

http://denethor.wlu.ca/ltspice/  (Tutorial and lots of good links)
 
LTspice is best for Analogue simulations in my opinion - The digital models are a pain.
 
For anyone having problems downloading LTspice, I have attached it to this message.. Probably not something I should be doing.. but as I am promoting their software, I hope Linear Technology wont object!

  • I went to the Linear Tech site and started to download the LTSpice installer. I was told that my email address is insufficiently sweet smelling. Their list of rejects includes gmail.com, hotmail.com and yahoo.com. OK, I can see their point.

     

    They allow that they might register you if you write to them, so I copied the page, after replacing my password choice with spaces, and wrote to them. We'll see what comes of it.

     

    In the mean time, I think I'll see how bad a time MultiSim (the free version from Analog Devices) does on understanding LTSpice files. At least I haven't been rejected by them (yet).
