Linear Circuits 1 - 21 - Operational Amplifiers, Part 1

This is day 21 of a full Linear Circuits series, covering the lecture material a sophomore-level circuits class would spend on operational amplifiers — the building blocks behind an enormous range of electronic circuits.

What it covers

Op amp circuits can look intimidating at first glance, so this lesson focuses on three basic laws that hold true for all ideal op amps. Once you know them, you can simplify and solve op amp circuits far more quickly than by brute-force circuit analysis.

Who it's for

Best suited to students already working through a linear circuits curriculum — either alongside a formal course or as a standalone refresher on operational amplifier fundamentals — rather than complete beginners to circuit theory.

Takeaway

A focused, single-topic lesson rather than a full course, useful for shoring up one specific concept in a broader circuits education.
