Control Loops
H(s), pole-zero plots, classical feedback, phase margin, compensator design, and root locus — the original scrolling series, now labeled as a mini tutorial.
Short, ordered interactive tracks — one focused topic, a few parts, tools embedded along the way. Bigger MIT-style courses live on the courses catalog; mini tutorials are the “I have an hour” lane.

From what you see on a scope (random, bandwidth-limited fuzz) through Vrms, uncorrelated summation, and noise spectral density — ending with the Noise Band Explorer.
Need for matching, Z and Γ, series/shunt paths, reading the Smith chart — then the full matcher lab.
Why regulate, energy and FETs/GaN, LDOs and feedback, buck/boost/buck-boost/inverting, SEPIC and Ćuk, losses, min on-time, DC vs transient requirements.
