Semiconductor Devices and Circuits is aimed at undergraduate students of engineering for an introductory course on devices & circuits. The book covers in detail the basic theories and principles of both devices and circuits. Beginning with the fundamental concepts, the book gives an exhaustive coverage of topics such as basic semiconductor physics, crystal sturctures, junction diode, bipolar junction transistor, MOS capacitor, MOSFET, baising, frequency response of amplifiers, and operational amplifiers. Written in a very lucid and student-friendly style, the book contains plenty of solved examples interspersed in the text for easy understanding of concepts. References have also been given at the end of the book for students interested in further reading of the topics. Numerous exercises at the end of each chapter challenge readers to test their understanding of concepts.About the Author: Dr. Aloke Dutta is currently a professor in the Department of Electrical Engineering at IIT Kanpur.
