Getting an Op Amp Integrator to Clip

Damn...I still have stuff to learn in electronics. Which still makes it fun. I get bored if I know too much.. :)

I do have this integrator in a loop and have (now using the proper term) observed 'wind up' in spice.

Spice for sure... I was never was good at understanding circuits with multiple feedback loops.

I kinda get that circuit.. For Vout to clip at 2.6V, the non-inverting input feed is such that the difference * Av = 2.6V. I'll probably figure out the rest later..

A very different solution from my point of view.. Thanks..

Simplify your life by assuming that everything I say is official.

for a real low frequency one you could use a microprocessor with a DAC some some counter timers and an ADC.
