Electronic Concepts provides a detailed introduction to modern microelectronics. Jerrold Krenz emphasizes analog and digital circuits, and describes applications of particular devices and circuits within the context of actual electronic systems. He begins with an overview of several important electronic systems, and discusses in detail the types of signals that circuits are used to process. The following chapters deal with individual devices. For each device Krenz presents a brief physical description and demonstrates the use of different models in describing the device's behavior in a particular circuit application. He uses SPICE computer simulations throughout the text to supplement analytic descriptions. The book contains over 500 circuit diagrams and figures, over 400 homework problems, and over 100 simulation and design exercises. Laboratory experiments are available via the World Wide Web. With its many worked examples, the volume is an ideal textbook for introductory courses in electronics.
