This is a simple saw tooth wave form as part of a PWM design that I am working on. I can set the the max voltage with the pot, but the min voltage is a problem, in this SIM, I am using 8 1N916 diodes in series.
I can make an adjustable current limit out of a LM317 and a constant current out of a JFET, J310, but I don't know how to make an adjustable zener. Any one have any suggestions?
Thanks,
Jeff
