In an inverting input op-amp, differentiator supplied with a ramp or triangular wave, the output is a:
A)opposite phase ramp.
B)same phase square wave.
C)sine wave.
D)opposite phase square wave.

Question

Quizplus · Accepted Answer

An inverting differentiator op-amp circuit outputs a square wave when supplied with a ramp or triangular wave input, and the output is 180 degrees out of phase with the input, hence an opposite phase square wave.
