Differential And Audio Amplifier Circuits: Basic Foundation: Common Mode Rejection Audio (Paperback)

Description

A differential amplifier is a type of electronic amplifier that amplifies the difference between two input voltages but suppresses any voltage common to the two inputs. An amplifier or electronic amplifier is an electronic device that can increase the power of a signal (a time-varying voltage or current). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a proportionally greater amplitude signal at its output. Both of them contribute an important function in engineering.

This book is a very short introduction to differential and audio amplifier circuits. The first part of the book covers transistor differential amplifiers, while the second (chapters 8 - 11) is concerned with the design and analysis of a fully functional audio amplifier circuit. The audio amplifier features a differential amplifier stage at its center, and therefore the second part of the book flows naturally from and builds on the first.
