Hello,
I'm having a problem to determine the accurate zero crossing of my folding signals. When i compare the ideal zero crossing with the simulate zero crossing there is a deviation aroun 3mV. I have tried to make the size of differential pair transistor larger but i still cannot get the value which is close to ideal. There is always an offset. Anyone have idea on how to solve this?
