This book is an outgrowth of a set of notes prepared by the author for the first and second year of undergraduate students of various disciplines of engineering and applied sciences, such as electro-nics, computer science, and information technology. The text aims at giving clear and simplified explanations on the physical construction, relevant characteristics, principles of operation, and applications of several currently and widely used devices in electronic industries and research fields. As far as possible, mathematics is completely avoided. However, simple mathematical analyses are made in situations as and when they are required.
Designed as a textbook for undergraduate students in Electrical Engineering, Electronics, Computer Science, and Information Technology, this up-to-date, well-organized study gives an exhaustive treatment of the basic principles of Digital Electronics and Logic Design. It aims at bridging the gap between these two subjects. The many years of teaching undergraduate and postgraduate students of engineering that Professor Somanathan Nair has done is reflected in the in-depth analysis and student-friendly approach of this book. Concepts are illustrated with the help of a large number of diagrams so that students can comprehend the subject with ease. Worked-out examples within the text illustrate the concepts discussed, and questions at the end of each chapter drill the students in self-study.
Designed as a text for undergraduate students of engineering in Electrical, Electronics, and Computer Science and IT disciplines as well as undergraduate students (B.Sc.) of physics and electronics as also for postgraduate students of physics and electronics, this compact and accessible text endeavours to simplify the theory of solid state devices so that even an average student will be able to understand the concepts with ease. The authors, Prof. Somanathan Nair and Prof. S.R. Deepa, with their rich and long experience in teaching the subject, provide a detailed discussion of such topics as crystal structures of semiconductor materials, Miller indices, energy band theory of solids, energy level diagrams and mass action law. Besides, they give a masterly analysis of topics such as direct and indirect gap materials, Fermi–Dirac statistics, electrons in semiconductors, Hall effect, PN junction diodes, Zener and avalanche breakdowns, Schottky barrier diodes, bipolar junction transistors, MOS field-effect transistors, Early effect, Shockley diodes, SCRs, TRIAC, and IGBTs. In the Second Edition, two new chapters on opto-electronic devices and electro-optic devices have been added. The text has been thoroughly revised and updated. A number of solved problems and objective type questions have been included to help students develop grasp of the contents. This fully illustrated and well-organized text should prove invaluable to students pursuing various courses in engineering and physics. DISTINGUISHING FEATURES • Discusses the concepts in an easy-to-understand style. • Furnishes over 300 clear-cut diagrams to illustrate the discussed. • Gives a very large number of questions—short answer, fill in the blanks, tick the correct answer and review questions—to sharpen the minds of the reader. • Provides more than 200 fully solved numerical problems. • Gives answers to a large number of exercises.
