Hi,
I implemented the circuit in the attached schematic and am getting the expected +-1.3V triangle wave. However, it looks like there is a lot of noise or ringing on the triangle. When I zoom in to the attached scope screenshot, it looks like there are little sine waves moving along the ramp.
Is this a problem with my equipment or implementation? I'm using the ground leads that came with the probes. Besides that, I'm using a +-9V power supply and a function generator for the square wave input.
Thanks,
Carl
