This circuit is supposed to create a clean, linear, symmetrical saw tooth wave. The problem is that there is a small "glitch" in the waveform as shown in the attached drawing. Anyone have any idea why this small "step" appears near the top of the positive-going slope of the wave?
I'm using an LM324 quad O/A chip. I've used this circuit in the past using a longer (10 second) ramp time and had no noise problems.
