The switched-current technique is heralding a new era in analogue sampled-data signal processing. Unlike switched-capacitor circuits, switched-current circuits do not require linear floating capacitors or operational amplifiers and they are giving a renewed impetus to mixed-signal VLSI on standard digital technology. Key analogue designers from industry and academia worldwide have contributed to this first, very timely book entirely devoted to switched current analogue signal processing.

The book introduces the basic switched-current technique, reviews the state-of-theart and presents practical chip examples. Numerous application areas are described, ranging from filters and data converters to image processing applications. It also gives a very comprehensive treatment of the fundamental principles of switched-current circuits and systems.

The material in this book will be of benefit to students, both undergraduate and postgraduate, and researchers and circuit designers in academia and the electronics industry.
