The technology and applications which deal with the flow, emission and control of electrons in vacuum and matter is known as electronics. The discipline of electrical engineering which is concerned with the designing of electronic circuits, devices, VLSI devices and their systems is referred to as electronic engineering. It utilizes the active and non-linear electrical components including semiconductor devices like transistors, diodes and integrated circuits. The passive electrical components that are based on the printed circuit boards are also designed in this field. There are primarily two types of circuits which are studied within this field, namely, analog circuits and digital circuits. Electronic engineering encompasses various sub-fields such as consumer electronics, digital electronics, embedded systems, analog electronics and power electronics. This book is a compilation of chapters that discuss the most vital concepts in the field of electronic engineering. Some of the diverse topics covered in it address the varied branches that fall under this category. This book is an essential guide for both academicians and those who wish to pursue this discipline further.
