This book will guide the reader away from simple diode circuits through the analysis and design of various transistor and FET amplifier configurations. Analysis and design of various feedback and generator topologies were also considered. Throughout the book, an intuitive and heuristic understanding of the concepts and physical meaning of mathematical results is emphasized. Methods for solving problems are given in each chapter to assist the reader in analyzing schemas. This book contains almost 270 design-oriented working examples, as well as problems with varying degrees of complexity. A significant amount of exercise is included at the end of each chapter for self-testing. With a simplified and systematic approach to complex theoretical concepts, this book can serve as an excellent reference for design engineers.
