1. Introduction to Operational Amplifiers
Operational amplifiers (Op-Amps) are essential components in analog electronics, designed to amplify the difference between two input voltages. The chapter covers ideal and practical characteristics of Op-Amps, including applications in amplification, filtering, comparators, and more. It highlights the differences between Op-Amps and other amplifiers while also discussing practical design considerations.
