This book is based on the principle that an understanding of devices and circuits is most easily achieved by learning how to design circuits. The text is intended to provide clear explanations of the operation of all important electronics devices generally available today, and to show how each device is used in appropriate circuits. Circuit design and analysis methods are also treated, using currently available devices and standard value components. All circuits can be laboratory tested to check the authenticity of the design process. Coverage includes: Diodes, BJTs, FETs, Small-Signal Amplifiers, NFB Amplifiers, Power amplifiers, Op-Amps, Oscillators, Filters, Switching Regulators, and IC Audio amplifiers.
