Op Amps: The Differentiator
Channel: Electronics with Professor Fiore
Date: 2021-02-26

Here we examine the op amp differentiator. It is based on the parallel-parallel inverting amplifier but uses a capacitor in the Ri position. This results in an output voltage that is proportional to the derivative of the input voltage (i.e., its slope).
