Audio Power Amplifier Design

An essential book for amplifier designers and engineers, enabling them to develop reliable, high-performance circuits. Douglas Self covers the major issues of distortion and linearity, power supplies, overload, DC-protection, and reactive loading. He also covers unusual forms of compensation and distortion produced by capacitors and fuses. The only book with in-depth coverage of design and development of audio power amps. Using a design methodology, Self makes it possible to predict practical performance from a theoretical design. This edition includes new coverage of Class D amps, comprehensive updates on technological developments, illustrations of sample circuits, SPICE models, and concise summaries of design guidelines.

This is the essential book reference for amplifier designers. Douglas Self covers all the design issues of noise, distortion, power supply rejection, protection, reliability, and layout. He describes advanced forms of compensation that give dramatically lower distortion.

This edition is much expanded, and packed with new information. It is a must-have for audio power amplifier professionals and audiophiles, amateur constructors and anyone with intellectual curiosity about the struggle towards technical excellence.

New to the sixth edition:

• The characteristics of the audio signal
• The principles of distortion
• Feedback intermodulation distortion
• Non-switching output stages
• VAS distortion explained
• Push-pull VAS configurations
• Output-inclusive compensation

In addition, five amplifier design examples that illustrate important design principles are examined and measured in detail. These can be straightforwardly adapted to specific requirements.

This new edition also includes a wealth of material on the XD crossover-displacement principle (invented by the author and in use by Cambridge Audio), four-stage amplifier architectures, error correction, current-mirrors, power transistors with internal sensing diodes, amplifier bridging, input-stage-common-mode distortion, amplifier stability, output stages with gain, inrush current suppression, DC servo design, thermal protection, cooling fan control, advanced line input stages, testing and safety, infrared remote control, signal activation, 12V trigger control, the history of solid-state amplifiers and much more. Simple procedures for heatsinking and power supply design are given.
