Op-Amp Amplifiers: The Two Ideal Rules, Inverting and Non-Inverting Gain, the Follower & Resistor Pairs
This lesson is part of the course
In this lesson
You compute gain and output of four op-amp stages from their resistors, see the follower as a non-inverting stage with Rf = 0, then choose the feedback resistor from a fictional series that gets closest to a target gain.
