Op-Amp Integrator

  1. Sep 2, 2007 #1
    Hey there

    This should be nice and simple. Here's the deal-- I was asked to design an Op-Amp Integrator circuit. For a 500Hz square wave input signal that oscillates from +/-0.5v, I was asked to design for a triangle wave output which oscillates from 0 to -5 volts.

    I designed the circuit just fine, only problem is that it oscillates from about 0 to 5 volts instead of 0 to -5. I know these circuits have small offsets, so it's not exactly 0 to 5, but close enough. This is a stupid question, but I need a DC offset. I was under the impression that I could just stick a dc voltage source somewhere whose difference would bump the signal down some. But to no avail.

    My R is 100 ohms and my C is 1uF-- which works perfectly in PSpice.

    Any suggestions?

    Do you need an offset or an inverter? Just wanted to check this since it seems from your description that you need an inverter...
