Fundamentals of Microelectronics, 3rd Edition, is a comprehensive introduction to the design and analysis of electrical circuits, enabling students to develop the practical skills and engineering intuition necessary to succeed in their future careers. Through an innovative “analysis by inspection” framework, students learn to deconstruct complex problems into familiar components and reach solutions using basic principles. A step-by-step synthesis approach to microelectronics demonstrates the role of each device in a circuit while helping students build “design-oriented” mindsets.
The revised third edition covers basic semiconductor physics, diode models and circuits, bipolar transistors and amplifiers, oscillators, frequency response, and more. In-depth chapters feature illustrative examples and numerous problems of varying levels of difficulty, including design problems that challenge students to select the bias and component values to satisfy particular requirements. The text contains a wealth of pedagogical tools, such as application sidebars, chapter summaries, self-tests with answers, and Multisim and SPICE software simulation problems. Now available in enhanced ePub format, Fundamentals of Microelectronics is ideal for single- and two-semester courses in the subject.
Behzad Razavi received the B.Sc. degree in electrical engineering from Sharif University of Technology in 1985, and the M.Sc. and Ph.D. degrees in electrical engineering from Stanford University in 1988 and 1992, respectively. He was with AT&T Bell Laboratories and subsequently Hewlett-Packard Laboratories until 1996. He was also an Adjunct Professor at Princeton University from 1992 to 1994. Since September 1996, Dr. Razavi has been an Associate Professor, and subsequently Professor, of the Electrical Engineering Department at UCLA. He was the Chair of the Integrated Circuits and Systems field of study, and served as Chair of the Department's Annual Research Review for two consecutive years.
Prof. Razavi is a member of the Technical Program Committees of Symposium on VLSI Circuits and the International Solid-State Circuits Conference (ISSCC), in which he is the chair of the Analog Subcommittee. He has served as Guest Editor and Associate Editor of the IEEE Journal of Solid-State Circuits, IEEE Transactions on Circuits and Systems, and International Journal of High Speed Electronics.
Professor Razavi's current research includes wireless transceivers, frequency synthesizers, phase-locking and clock recovery for high-speed data communications, and data converters.
