Differentiator

Our Take

An op-amp configured to differentiate the signal that is coming in. Much as a differential measures the angle of a curve in calculus, a differentiator will output how much the input is changing. For example, if the input is steady, the output will be zero. If the input is changing linearly, the output will be a constant equal to the rate of change.

Book Definition

An op-amp differentiator simulates mathematical differentiation, which is a process of determining the instantaneous rate of change of a function.
