Uses a practical, building-block approach presenting basic circuitry concepts such as gain, frequency response, multistage amplification, feedback, and oscillation. 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. Features extensive coverage of SPICE -- including examples and exercises in every chapter to show its application to every aspect of devices and circuit theory.
