Analog and digital electronic are one of the core course sequences in the electrical, electronics and computer engineering. As a gateway to the exciting and rapidly growing field of microelectronics, it is essential that these courses be taught well, both for future specialists and for those concentrating in other areas of electrical engineering or computer science.This book is for everyone who wants to design and study of real digital circuits.It is based on the idea that, in order to do this, you have to grasp the fundamentals, but at the same time you need to understand how things work in the real world. In the past, when digital designers were building systems with thousands or at most tens of thousands of gates and flipflops, academic courses emphasized minimization and efficient use of chipand board-level resources. Today, a single chip can contain tens of millions of transistors and can be programmed to create a system-on-a-chip that, using the technology of the past, would have required hundreds of discrete chips containing millions of individual. This book must provide a solid foundation in the fundamentals of electronics rather than a sampling of the most popular current topics.Finally, circuit design, as its name implies, is a subject that should be wellsuited for honing students skills as engineering designers. All of these factors have forced a re-examination of the electronics sequence and opened the door to fresh approaches that are better adapted to the needs of students.
