The objective of the Analog Audio Amplifier Design is to develop in the reader the ability to analyze and design analog audio amplifiers using operational amplifiers, discrete semiconductor transistors, and vacuum tubes. The book is written to address many advanced topics and practical amplifier configurations. However, it also provides the necessary basics, examples and exercises that allow the readers to progressively absorb the materials of the book and gain confidence in using various design techniques.

Analog Audio Amplifier Design introduces all the fundamental principles of analog audio amplifiers, alongside practical circuit design techniques and advanced topics. Covering all the basics of amplifier operation and configuration, as well as high-end audio amplifiers, this is a comprehensive guide with design examples and exercises throughout.

With chapters on single-device, operational, multi-stage, voltage buffer, power, line-stage and phono-stage amplifiers, Analog Audio Amplifier Design is a comprehensive and practical introduction that empowers readers to master a range of design techniques. This book also provides a variety of graphs and tables of key amplifying devices and properties of amplifier configurations for easy reference.

This is an essential resource for audio professionals and hobbyists interested in audio electronics and audio engineering, as well as students on electrical and audio engineering courses.

There are 14 chapters in this book, which cover amplifier designs ranging from basics of amplifiers, operational amplifiers, phono-stage amplifiers, line-stage amplifiers, and power amplifiers. The use of semiconductor transistors and vacuum tubes are fully discussed.

Chapter 1 covers the basics of the audio components that make up a typical Hi-Fi system. The audio components include the phono-stage amplifier, line-stage amplifier, and power amplifier, as well as the dc regulated power supply.
Chapter 2 covers the dc analysis for five commonly used amplifying devices. They are: solid-state bipolar junction transistor (BJT), junction field-effect transistor (JFET), enhancement type metal-oxide field-effect transistor (MOSFET), depletion type MOSFET, and vacuum tube triode. DC bias techniques, including fixed-bias, voltage-divider bias, and self-bias are discussed.
Chapter 3 covers the ac analysis of amplifying devices in response to a sinusoidal signal. Several small signal ac models are used to represent the devices. Hybrid-pi and T-model are two popular ac models used for BJTs and FETs.
...
In Chapter 13, hybrid power amplifiers design is presented. The hybrid power amplifiers employ vacuum tubes for the input stage and voltage amplifier stage, while solid-state power devices are utilised for the output stage. Several examples of hybrid power amplifier design are given.
The final chapter, Chapter 14, covers dc regulated power supplies design. The chapter starts by describing three-terminal dc regulators, including fixed voltage and adjustable voltage type. Then shunt type and series type regulated power supplies employing discrete solid state devices, vacuum tubes, and a hybrid approach are discussed.
