Author Saw 2 Triangle Conversion (using ideal diode circuit)

yesterday i built this in spice during my lunch brake after reading jim patchell's ideal diode circuit. it will work with falling/rising ramp, even with only positive going ones (that's what i need it for). however, i've had no chance to listen to it right now.
BTW depending on your application/raw material the first trimmer will have to be wired between the rails.

And Jim certainly didn't invent the ideal diode!
