Analog Electronics — Op-Amps & Fundamentals
Curated: learn the op-amp and analog-signal fundamentals from a top free course, prove it in Forge, and get certified. The analog counterpart to the Embedded track — the part of a product that lives before the ADC.
Operational Amplifier (Op-Amp) — Linear Integrated Circuits Playlist
ALL ABOUT ELECTRONICS (Rushal Shah) · video · ~14h · Free · English
Why we picked it: ALL ABOUT ELECTRONICS is one of the most-subscribed channels dedicated purely to electronics teaching (~792K subscribers, 470+ videos), run by Rushal Shah (M.Tech, IIT Delhi). Its 81-video op-amp playlist is the most complete free op-amp series on YouTube and is repeatedly the top-recommended op-amp resource on Class Central and engineering forums. It starts from the ideal op-amp and builds up slowly — perfect for a beginner — while still covering every configuration, the gain math, and active filters.
- the ideal op-amp and its characteristics (infinite gain, virtual short, no input current)
- inverting and non-inverting amplifier configurations and their gain equations
- the voltage follower / buffer and why impedance matching matters
- summing, difference (differential) and instrumentation amplifiers
- comparators and the op-amp running open-loop (saturation to the rails)
- integrator and differentiator circuits
- active filters built with op-amps (low-pass / high-pass / band-pass)
- real op-amp limits: input offset, slew rate and gain-bandwidth product
