Builds classical feedback control design from a real operational amplifier's behaviour rather than an abstract block diagram, arguing that intuition for stability, noise and nonlinearity is best built from a physical circuit before it is generalised.

Derives a fixed mathematical relationship between a feedback amplifier's gain and phase response, showing a designer cannot choose one without constraining the other — the basis of the gain and phase margins read off a Bode plot ever since.
