Diode rectification and clamping, BJT and MOSFET DC biasing and small-signal models, op-amp topologies, negative feedback theory, active filters, basic oscillators, and the real-world limits — offset voltage, noise, gain-bandwidth trade-offs, and slew rate — every analog design runs into.
Module 1 established the PN junction and carrier physics that make a diode, a BJT, and a MOSFET behave the way they do at the device level. This module puts that physics to work: diode rectifiers and clamps, biased BJT and MOSFET amplifier stages and the small-signal models used to analyze them, and the op-amp topologies — inverting, non-inverting, differential, and instrumentation — built from those same devices at a higher level of abstraction.
By the end of this module you should be able to explain why negative feedback trades gain for bandwidth in a predictable, quantifiable way, and why a signal well within an op-amp's small-signal bandwidth can still distort at high amplitude because of a completely separate limit, slew rate. Module 9 (Signal Integrity) and Module 11 (High-Speed Design) both revisit these same amplifier and bandwidth limits later in the program, from a system rather than a single-stage perspective.
