Preface

The material in this book is presented in a logical manner. More emphasis has been laid on the principles of electronics and their circuit aspects. All the fundamental concepts of electronic devices and circuits are covered with necessary illustrations and numerical problems. A large number of numerical problems are also solved for providing better understandability to the students.

A distinctive feature of this book is the inclusion of all the material needed for understanding the basic concepts in electronics. Proper care has been taken in deriving necessary equations to provide detailed information to the students. The circuit diagrams, graphs, equivalent circuits, mathematical modelling and approximations on diodes, bipolar junction transistors (BJTs) and field effect transistors (FETs) are dealt in an interesting manner. The sequence framed by the authors in covering the topics is in a coherent order.

Every attempt has been made to ensure that the book addresses all the requirements of the students, and thereby serve as a comprehensive textbook of electronics at the basic graduate level. The authors feel that undergraduate students will be much benefited in understanding the principle of electronics by going through this book. The introductory chapters provide the necessary mathematical background required for the remainder of the book. This book gives exposure to the elementary notions in the basic structure of electronics. The applications of electronics are also examined in the text. The authors, however, have been sensitive to new techniques that are fundamental in nature, and have therefore added appropriate material to keep the students up-to-date with recent developments in the field of electronics.

It is hoped that this unique textbook, comprising all the special features brought in by making use of the long experiences of the authors in the field of electronics, will prove to be an ideal textbook for engineering students at the undergraduate level, especially those pursuing a course in electrical, electronics and telecommunications and computer engineering. It will also serve the requirements of practising engineers as a reference book.
