An Analytical Approach to Linear Audio Frequency Power Amplifier Design: Selected Papers: Fourth Edition Paperback – November 11, 2025

This book is essential reading principally for designers of linear audio frequency power amplifiers and more generally for students and amateur enthusiasts of audio frequency electronics.A first-principles analytical approach is here preferred because it engenders an intuitive appreciation of the workings of linear audio frequency power amplifiers, and it provides the engineer and researcher with a sound foundation for further work in the field.Among other matters, the author cogently and succinctlyEvaluates the merits and demerits of two pole Miller minor negative feedback loop frequency compensation (TPMC) and localised two pole Miller minor negative feedback loop frequency compensation (LTPMC) and develops clear, systematic means by which these frequency compensation networks may be optimised.Tenders three novel feedforward-compensated push-pull folded cascode transimpedance stage (TIS) designs in which slew asymmetry is banished.Renders four novel feedforward-compensated push-pull transimpedance stage (TIS) designs based on the complementary emitter-coupled transistor pair of Sziklai and Lohman.Assesses the value of Burwen’s Inductive Frequency Compensation (IFC) in context.Presents seven idiosyncratic audio frequency power amplifier designs compensated with optimised LTPMC networks and incorporating non-invasive anti-saturation measures.Examines monolithic/discrete composite linear audio frequency power amplifiers and their frequency compensation.Describes how Safe Operating Area (SOA) protection networks may be correctly and accurately designed so that they remain inert when the amplifier does not require protection.Gives an account of error feedback correction and presents four novel feedback error correction circuits.Discusses output-stage-inclusive single pole Miller minor negative feedback loop frequency compensation (OSI-SPMC).Reveals the utility and pitfalls of catching diodes in the context of the transadmittance stage (TAS), the complementary emitter-coupled transimpedance stage (TIS) and the differential folded cascode TIS.Considers the benefits and deficiencies of current mirrors in linear audio frequency power amplifiers.Exposes the idiosyncrasies of linear audio frequency power amplifiers with common-emitter output stages.The author gives all credit to Almighty God, the fount of all knowledge and without whom nothing is possible, through His son, Jesus Christ.Finally, the author hopes devoutly that adopters of this book will derive as much pleasure from reading it as he did from writing it.
