Electronics play a central role in our everyday lives, being at the heart of much of today's essential technology - from mobile phones to computers, from cars to power stations. As such, all engineers, scientists and technologists need a basic understanding of this area, whilst many will require a far greater knowledge of the subject. The third edition of "Electronics: A Systems Approach" is an outstanding introduction to this fast-moving, important field. Fully updated, it covers the latest changes and developments in the world of electronics. It continues to use Neil Storey's well-respected systems approach, firstly explaining the overall concepts to build students' confidence and understanding, before looking at the more detailed analysis that follows. This allows the student to contextualise what the system is designed to achieve, before tackling the intricacies of the individual components. The book also offers an integrated treatment of analogue and digital electronics highlighting and exploring the common ground between the two fields. Throughout the book learning is reinforced by chapter objectives, end of chapter summaries, worked examples and exercises. This third edition is a significant update to the previous material, and includes: New chapters on Operational Amplifiers, Power Electronics, Implementing Digital Systems, and Positive Feedback, Oscillators and Stability . A new appendix providing a useful source of Standard Op-amp Circuits New material on CMOS, BiFET and BiMOS Op-amps New treatment of Single-Chip Microcomputers A greatly increased number of worked examples within the text Additional Self-Assessment questions at the end of each chapter Dr. Neil Storey is a member of the School of Engineering at the University of Warwick, where he has many years of experience in teaching electronics to a wide-range of undergraduate, postgraduate and professional engineers. He is also the author of "Safety-Critical Computer Systems" and "Electrical and Electronic Systems" both published by Pearson Education.
