3. Op-Amp Feedback Configurations

Operational amplifiers (Op-Amps) utilize feedback to manage circuit behavior, and primarily negative feedback is employed for gain stabilization, linearity, and bandwidth enhancement. The chapter explores three main configurations: inverting, non-inverting, and differential amplifiers, detailing their circuit designs, gain equations, and applications. Real-world design examples are provided for practical understanding of these configurations.
