Electronic Devices and Circuits provides a comprehensive account on electronic devices and circuits and is as ideal for students pursuing undergraduate and postgraduate courses in electronics, as it is for aspiring professionals in the electronics industry. The book is comprised of two parts and begins with a discussion on the laws of quantum mechanics and their influence on the operation of electronic devices. It covers basic electronic devices such as semiconductors, bipolar junction transistors and field effect transistors in the first part and examines the application of these devices in electronic circuits, in the second. Replete with numerical examples, numerical exercises, MCQs and short- and long-answer questions, the book is designed to hone the student’s understanding of the subject.
