Preface This book is intended for use in the core electronics courses for undergraduate electrical and computer engineering majors. The book frequently takes the designer''s point of view in discussing circuits, illustrates design with numerous examples, shows how to test circuit designs using SPICE, and provides numerous open-ended design problems with which students can practice. WHAT''S NEW IN THE SECOND EDITION The entire book has been reorganized and rewritten with an eye toward reducing its length and making it more student friendly. Integrated-circuit techniques are treated earlier and receive greater emphasis throughout. The needs of computer-engineering students are addressed by treating the switching behavior of devices early in the book, adding a chapter on CMOS logic circuits, and adding a discussion of data converters. Several motivational examples are provided in the "Anatomy of a Design" sections as asides from the main text to show how interesting circuits can be designed using the material learned to that point in the book. For example just after the chapters on op-amps and diodes, the design of a function generator is illustrated. The introduction and the treatment of external amplifier characteristics have been condensed into the first chapter. MOSFETs are emphasized over JFETs. Op-amps are treated in a single chapter. The treatment of device physics has been shortened and appears in the various chapters on an as needed basis. The chapter on SPICE has been eliminated because most students learn to use SPICE in their circuits courses. ASSUMED BACKGROUND AND LEVEL OF PRESENTATION The background assumed is a first course in circuit analysis. In the beginning, the level of presentation is appropriate for an introductory core course. Starting with Chapter 7, the level gradually increases to that appropriate for juniors having a stronger interest in the subject. Circuit analysis by Laplace transform methods is helpful (but not required) background for frequency response and compensation of feedback amplifiers in Chapter 9. INSTRUCTIONAL AIDS A website located at http://www.prenhall.com/hambley contains a number of resources for instructors and students including: Answers to selected end-of-chapter problems PDF files of key figures from the book that can be used to make transparency masters Schematic files for the circuits discussed in the book Schematic files that are the answers to Exercises that call for SPICE analysis A selection of links to manufacturers'' sites where additional data may be downloaded A solutions manual containing complete solutions for the exercises and problems is available to instructors who adopt the textbook for classroom use.

The address of the publisher is: Electrical and Computer Engineering Editor Prentice Hall 1 Lake Street, Upper Saddle River, NJ 07458 CONTENT This book supports a wide variety of course plans. More than enough material is provided for a two-semester (or three-quarter) course sequence, allowing topic selection suited to the interests of the instructor and students. Chapter 1 contains an overview of electronics and treats the external characteristics of amplifiers. The first several sections acquaint students with the big picture and illustrate how the details studied in this book fit into that picture. Usually, I assign this material for reading but don''t spend class time on it. Next, we introduce basic amplifier concepts including gain, input resistance, output resistance, frequency response, and circuit models for amplifiers. The chapter concludes with a discussion of differential amplifiers, setting the stage for op-amps. Chapter 2 treats operational amplifier circuits including basic amplifiers, imperfections of op-amps, integrators, and differentiators. The discussion of amplifiers gives immediate application for the concepts (that were introduced in Chapter 1) of gain, input resistance, output resistance, and ideal amplifier types. Chapter 3 treats diodes and diode circuits, including load lines, ideal diodes, rectifiers, wave shapers, logic circuits, voltage regulators, device physics, and switching behavior. The small-signal-equivalent-circuit concept is introduced in Section 3.8 setting the stage for BJT and FET amplifier analysis. "Anatomy of a Circuit Design: A Function Generator" is set aside from the main text and appears between Chapters 3 and 4. It shows students how the material from the first three chapters can be used in designing a useful and interesting circuit. Chapter 4 covers BJT characteristics, load-line analysis, large-signal models, biasing, small-signal equivalent circuit analysis, the common-emitter amplifier, the emitter follower, and use of the BJT as a switch in logic circuits. Chapter 5 contains a similar treatment of FETs with the main emphasis on MOSFETs. If desired, the order of Chapters 5 and 6 can be reversed with little difficulty. "Anatomy of a Circuit Design: A Multistage Amplifier" appears immediately after chapter 5 and illustrates how a multistage amplifier can be designed using what was learned from Chapters 4 and 5. Chapter 6 treats digital logic circuits with very strong emphasis on CMOS. Basic logic circuit concepts, the resistor-pull-up NMOS inverter, the CMOS inverter, propagation delay, NOR and NAND gates, dynamic logic, and transmission gates are covered. Differential and multistage integrated amplifiers including IC bias techniques are treated in Chapter 7. Chapter 8 covers amplifier frequency response, including the Miller effect, the BJT hybrid model, and common amplifier configurations. Chapter 9 examines feedback and oscillators. Sections 9.1 through 9.4 deal with types of feedback and their effects on gain and impedances. Then several design examples are given in Section 9.5. Sections 9.6 through 9.9 treat transient response, frequency response, and compensation of feedback amplifiers. Several examples of feedback amplifiers are discussed in Section 9.10. Finally, oscillator principles are discussed in Sections 9.11 and 9.12. "Anatomy of a Circuit Design: A Cardiac Pacemaker" appears after Chapter 9 and shows an interesting application of many of the circuits and concepts discussed in the book. Output stages and power supplies are presented in Chapter 10 including thermal considerations, power devices, Class A and B amplifiers, linear voltage regulators, and power-supply design. Chapter 11 treats active filters, tuned circuits, impedance-matching networks, LCoscillators, and crystal oscillators. Chapter 12 considers comparators, timer circuits and data converters, including the Schmitt trigger, multivibrator circuits, the 555 timer IC, digital-to-analog converters, and analog-to-digital converters. Finally, "Anatomy of a Circuit Design: A Precision AC to DC Converter," illustrates another practical design using many of the concepts treated earlier in the book. CHAPTER DEPENDENCY The first five chapters form the foundation upon which the remainder of the book rests. The order of coverage of the remaining chapters is extremely flexible. Chapter 5 on MOSFETs can be covered before Chapter 4 on BJTs if desired.
