This volume of Analog Circuit Design concentrates on three topics: Low-Noise, Low-Power, Low-Voltage; Mixed-Mode Design with CAD Tools; Voltage, Current, and Time References. The book contains six papers on each topic, written by internationally recognised experts. The papers are tutorial in nature and make a substantial contribution to improving the design of analog circuits. The book is divided into three parts. Part I, `Low-Noise, Low-Power, Low-Voltage', concentrates on the problems of the matching properties of high frequency MOS circuits caused by the continuous reduction in the size of integrated devices. These problems are considered in light of maintaining the benefits of greater bandwidth and lower power consumption. Part II, Mixed Mode Design with CAD Tools', looks at the practicalities of providing CAD tools for circuits containing both digital and analog elements. The papers consider both the simulation and synthesis aspects of designing CAD tools suitable for such designs. Part III,Voltage, Current and Time References' contains much new and exciting material describing all aspects of these reference circuits. Audience: An essential reference source for analog design engineers and researchers wishing to keep abreast with the latest developments in the field. The tutorial nature of the contributions also makes it suitable for use in an advanced course.
