ANALOG ELECTRONICS (CIRCUITS AND DEVICES) Dr. D.K.Kaushik Head Department of Electronics and Computer Science, Dayanand Post Graduate College, Hisar (Haryana) Edited by: Dr. P.J.George Senior most Professor and Chairman, Electronic Science Department, Kurukshetra University, Kurukshetra (Haryana)
PREFACE The book Analog Electronics (Circuits and Devices) contains eleven chapters with comprehensive material, discussed in a very systematic, elaborative and lucid manner. The author of this book has made sincere efforts in bringing the book very up to date. It has thoroughly been edited by Prof. P. J. George, Senior Most Professor and chairman Electronic Science Department, Kurukshetra University, Kururkshetra. It will prove to be good text book for polytechnic and B.E./B.Tech. students of all the engineering colleges in India. It will also cater to the needs of the students of B.Sc. (Electronics), U.G.C. sponsored restructured course. The book also covers the syllabi of B.Sc. (IT), M.Sc.(Physics specialization in Electronics), M.Tech (electronics). The objective of this book is to enable students to understand basic circuits and devices. The discussion on the subject in adequate and after going through the book the students will not only have the fundamental knowledge but will have the overall knowledge. First three chapters of this book contain the circuit theory and deal the network analysis with d.c. and time varying sources and two port network. Different network theorems, different parameters of Two Port Network and their interconnections, different types of passive filters with their frequency and phase response curves have thoroughly and lucidly been discussed with typical solved problems. Next two chapters i.e. chapters 4 & 5 deal the physics of semiconductor, different types of semiconductor diodes including Zener diodes, photo diodes and light emitting diodes. The application of diodes such as different types of rectifiers, filters, voltage multipliers, and clipping, clamping and log antilog circuits have also been discussed. Complete theoretical aspects have been considered in these chapters. Chapters 6 – 8 contain the theory of transistors. These chapters cover physical behaviour of junction transistors their characteristics, base width modulation, models of the transistors along with transistor biasing and thermal stabilization with exhaustive analytical explanation.
