Control Loops
H(s), poles and zeros, loop gain and phase margin, compensator design, and root locus — one idea per page, tools along the way.
Short, ordered interactive tracks — one focused topic, a few parts, tools embedded along the way. This is the learning section of the site (the “I have an hour” lane).
H(s), poles and zeros, loop gain and phase margin, compensator design, and root locus — one idea per page, tools along the way.
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.
Sampling, aliases, quantization, ideal SNR, noise that folds, distortion, and DC errors. More parts (references, anti-aliasing, architecture) planned.
Stay inside the load’s voltage window, MOSFET as a switch, then why we switch: buck, boost, IBB, SEPIC, Ćuk, Zeta, flyback (when · operation · conducted ports), plus DCM / burst and the flyback transformer.
