This book is intended to serve as a textbook for the students taking the course on Basic Electronics (First Semester B.E.) prescribed by the VTU.
Fundamental principles and applications of electronics are described herein in a clear and concise way with explanatory diagrams. The language is lucid and simple. Physical aspects are explained with ample details; mathematical derivations are also given, where necessary. Numerical problems which are typically set in examinations are included in the book to illustrate the application of the principles contained in the text. Many of these problems are worked out, and the rest are left as exercises for the students. The answers to such problems are given for the benefit of the readers. The objective-type and the review questions included in the book reflect the type of such questions set in different examinations.
The book contains 13 chapters. Chapter 1 deals with semiconductor diodes. Diode applications are treated in Chapter 2. Chapters 3 and 4 are devoted to junction transistor characteristics, transistor biasing and amplification. Chapter 5 is concerned with field-effect transistors. Special devices like silicon-controlled rectifiers and unijunction transistors form the subject-matter of chapter 6. Basic amplifiers feedback in amplifiers and oscillators are discussed in chapters 7, 8, and 9, respectively. Operational amplifiers are taken up in chapter 10. Modulation and communication systems are included in chapter 11, Number systems and digital logic are covered in chapter 12. The cathode ray oscilloscope is incorporated in chapter 13.
About the Author(s):
Professor D. Chattopadhyay obtained his Ph.D. and D.Sc. degrees in Radio Physics and Electronics in 1972 and 1980, respectively, from the University of Calcutta. He was awarded the Mouat medal by the same university in 1985 on successful completion of the Premchand Raychand Studentship. He visited the Technical University in Trondheim, Norway as a Post Doctoral Fellow in 1973-74. He also visited the Max Planck Institute in Stuttgart, Germany, from time to time during 1980 and 1990 as a Guest Scientist. In 1991, he was invited as a Visiting Scientist to the International Centre for Theoretical Physics, Trieste, Italy. His research interest centres around Electronic Transport in Bulk and Low-Dimensional Semiconductor Structures. He has a number of publications in internationally reputed journals and has co-authored a few books for the undergraduate and postgraduate students. At present, he is working as a professor in the Department of Radio Physics and Electronics, Calcutta University.
