PREFACE This book is the offshoot of our rich experience of teaching a number of subjects in the area of Electronics for two decades. In this book, the various concepts of the subject are arranged logically and explained in a simple reader friendly language for proper understanding of the subject. A large number of problems with their step by step solution are provided for every concept. Illustrative examples are discussed to emphasize on conceptual clarity and typical applications are highlighted to strengthen them. This book takes you from simple diode circuits through the analysis and design of a variety of transistor ampli ers. Analyses of various feedback ampli ers, principle of working and applications of MOSFETs, IC Timers, PLLs and Function generation ICs have also been covered. This book concludes with Regulated power supplies wherein different types of voltage regulators and their analysis have been presented elaborately. This book provides a simpli ed and systematic approach to dif cult theoretical concepts in Electronic Circuits. It can serve as an excellent reference material for design engineers. Those of you who enjoyed reading our previous book titled Electronic Circuits would certainly enjoy this book too. Despite the delight taken by many reviewers in nding mistakes, a few typo errors have managed to slip through the sieve. This suggests that more await discovery by you. We suppose that is what second editions are for. U. B. Mahadevaswamy V. Nattarasu
