This book uses a structured, systems approach in its comprehensive coverage of devices and circuits. It is a modern, thorough treatment of the topics traditionally covered during a two- or three-semester course in electronic device theory. Topical selection is principally based on the significance of each topic in modern industrial applications and the impact that each topic is likely to have in emerging technologies. Integrated circuit theory is covered extensively, as are field-effect devices and their applications in large-scale integration, the theory of operational amplifiers—including many important applications of those versatile devices—optoelectronics, switching regulators, and class D amplifiers.
