13.1 INTRODUCTION
All the types of amplifiers discussed are designed for a specific application or use. They involve either transistor or FET circuits either in single or multi stage configurations. But, Operational Amplifier, known as Op-Amp, is an amplifier, which has a number of applications. Op-Amp is a cascade of large number of amplifier stages designed such ...
