Electronic Feedback

Lecture no. 12 from the course: Understanding Modern Electronics

Electronic Feedback

Taught by Professor Richard Wolfson | 35 min | Categories: The Great Courses Plus Online Science Course

Understand the math behind two basic rules that allow op-amps to leverage the magic of negative feedback: no current flows into op-amp inputs, and with negative feedback, V+ = V –. See how these rules allow op-amps to tame near-infinite gain in a circuit down to the exact amplification you want.
