Electronic Devices and Circuit Theory

Highly accurate and thoroughly updated, this classic has set the standard in electronic devices and circuit theory for over 25 years. Boylestad offers a complete and comprehensive survey, focusing on all the essentials needed to succeed on the job. Provides a colorful, reader-friendly layout that boasts a large number of stunning photographs. Integrates troubleshooting sections in most chapters, offering general hints on how to isolate a problem, identify its causes, and what action to take to rectify it. Includes over 40 new end-of-chapter practical examples added throughout. Expands coverage of computer software to include Mathcad, illustrating the versatility of the package for use in electronics. Adds summaries to the end of every chapter. Ideal for electronics professionals who want to brush up their software and troubleshooting skills.

In this edition we have written additional practical examples and summaries at the end of each chapter, and have expanded coverage of computer software. The chapter on IC construction was deleted and replaced with a well-written description of the process that first appeared inSmithsonian Magazine.It has some stunning photographs and content that is excellent for the new students of this rapidly changing field. Over the years we have learned that improved readability can be obtained through the general appearance of the text, so we are committed to the format you find in this and recent editions of the text. We hope you agree that it makes the text material appear "friendlier" to the broad range of students using the text. As in the past, we continue to be committed to the strong pedagogical sense of the text, accuracy, completeness, and a broad range of ancillary materials that support the educational process. PEDAGOGY Reviewers and current users appear to be quite satisfied with the manner in which the content lends itself to a typical course syllabus. The improved pedagogy of the last two editions seems to support the instructor's lecture and helps students build the foundation necessary for future studies. The number of examples continues to grow, and isolated boldface statements continue to identify important concepts and conclusions. Color continues to be employed in a manner that helps define important regions of characteristics, or identifies important regions or parameters of a network. Icons at the top of the page, developed for each chapter of the text, facilitate referencing a particular area of text as quickly as possible. Problems which have been developed for each section of the text, progress from the simple to the more complex. The title of each section is repeated in the problem section to identify the problems associated with a particular subject matter. SYSTEMS APPROACH There is no question that the growing development of packaged systems requires that the student become aware at the earliest opportunity of a "systems approach" to the design and analysis of electronic systems. Isolated no-load networks are first discussed in Chapters 8 and 9 to introduce the important parameters of any package and develop the important equations for the configuration. The impact of a source or load impedance on the individual package is then defined in Chapter 10 on a general basis before examining specific networks. Finally, the impact of tying the individual packages together is examined in the same chapter to establish some understanding of the systems approach. The later chapters on op-amps and IC units further develop the concepts introduced in these early chapters. ACCURACY The goal of any educational publication is to be absolutely free of errors. There is nothing more distressing to a student than to find that he or she has suffered for hours over a simple printing error. In fact, after all the hours that go into preparing a manuscript and checking every word, number, or letter there is nothing more distressing to an author than to find that errors have crept into the publication. Based on past history and the effort put into this publication, we believe you will find the highest level of accuracy obtainable for a publication of this kind. SUMMARIES In response to current users, summaries are added at the end of eactl chapter, reviewing the salient concepts and conclusions. To emphasize specific words and phrases, boldface lettering is used in much the same manner as a student would use a highlighting marker. The list of equations appearing with each summary was limited to those an instructor realistically hopes the student will bring away from the course. PRACTICAL EXAMPLES While the text now has over 80 practical examples, over 40 were added to this edition and they appear in their own sections. They provide an understanding of t
