Operational Amplifier Circuits | Chapter 13

Описание: In this video, we explore Chapter 13 of Microelectronic Circuits by Sedra and Smith, where the focus shifts to operational-amplifier–based circuits and how feedback amplifiers are configured to perform specific signal-processing functions.

This chapter builds on the foundations of feedback and op-amp behavior to show how real circuits such as integrators, differentiators, summing circuits, and other functional amplifier blocks are constructed and analyzed. It demonstrates how simple feedback networks transform a high-gain op amp into precise, predictable signal-processing elements.

Using clear visuals and intuitive explanations enhanced by modern presentation techniques, we walk through how these circuits work at a conceptual level—how signal flow, feedback paths, and component placement determine functionality, stability, and performance.

We focus on understanding why each configuration behaves the way it does, how ideal behavior differs from real-world operation, and how practical limitations such as bandwidth, saturation, and component non-idealities influence circuit performance.

Rather than relying on heavy mathematical derivations, the discussion emphasizes engineering intuition—how designers think about shaping signals, controlling system behavior, and selecting circuit topologies to meet real design goals.

This chapter provides essential insight for analog signal processing, control systems, and active filter design, and prepares you for more advanced applications of op amps in both discrete and integrated circuits. Whether you’re learning op-amp circuits for the first time or reviewing them from a design perspective, this video delivers a clear and practical explanation grounded in real engineering practice.
