2.7. amplifier circuits – discrete and IC

Welcome to the Chapter on Amplifier Circuits, focusing on both discrete components and integrated circuits (ICs). This course is designed to deepen your understanding of various amplifier configurations using Field-Effect Transistors (FETs) and bipolar transistors. Through this section, we will explore the intricacies of different amplifier types, including common-source, common-drain, and common-gate configurations for FETs, and their bipolar counterparts such as common-emitter, common-collector, and common-base amplifiers.

The section will delve into key aspects of these amplifiers, such as input and output impedance, phase relationships, and their analogies between FET and bipolar transistor designs. You’ll gain insights into why certain configurations are chosen for specific applications, how they influence signal processing, and their roles in various electronic circuits.
