Posted - 24 Apr 2007 : 03:40:14 I need a sawtooth generator for a simulation. How do I make one ? Using a arbitrary voltage source ? Been trying that but without success. Any help would be welcome.

Posted - 24 Apr 2007 : 05:08:00 Essentially you create a square wave generator, but customise the rise and fall times so that the end result is a sawtooth.
Use the pulse generator, specify your rise and fall times (SpiceRise, SpiceFall), set a pulse width (SpiceWidth) of zero, so there's no flat top, and set the period (SpicePeriod) to be the sum of the rise and fall times, so there's no flat bottom.
I won't go into more details, as they're in the manual. If you can't find your paper copy, run up the command shell, then go to [Help], [Online Manuals], [User's Guide]. You'll get a pdf version displayed.
