I've been trying to find a AC to DC converting circuit that will take a piezoelectric crystal as its input. I have the piezo to a bridge rectifier but all the diagrams I am finding have some kind of an IC to help smooth out and regulate the voltage(3-5v output is what i'm looking for).
I'm trying specifically without an IC as I am using circuit simulating software that does not have the IC models i'm finding referenced.
ideally i can build this circuit in software before I buy parts.
Thanks!

You want a zener regulator:
Software should have no problem simulating that. You do not need R -- piezo's internal resistance will be large enough.
