This volume of Analog Circuit Design concentrates on three topics: MOST RF Circuits; Bandpass Delta-Sigma Converters; Translinear Circuits. The book comprises six papers on each topic written by internationally recognised experts. These papers are tutorial in nature and together make a substantial contribution to improving the design of analog circuits. The book is divided into three parts: Part I, MOST RF Circuits, demonstrates the viability of using CMOS for high-frequency communication applications. This renaissance in radio-frequency design is largely driven by the explosion of interest in telecommunications and several of the papers are specifically targeted to wireless communication applications. Part II, Bandpass Delta-Sigma Converters, describes the latest developments in analog-to-digital and digital-to-analog converters. These converters find applications in telecommunications, hearing aids and audio systems, particularly when they consume low-power and have high performance. This part concludes by looking at the CAD tools required for the design of such converters. Part III, Translinear Circuits, have become important devices in building analog linear functions with variable parameters. This part of the book presents the latest research and techniques for designing Translinear Circuits using both bipolar and CMOS technologies. Analog Circuit Design is 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.
