Summary: This new edition introduces novel analysis and design techniques for delta-sigma ((SEV(B) converters in physical and conceptual terms, and includes new chapters that explore developments in the field over the last decade. This book explains the principles and operation of delta-sigma analog-to-digital converters (ADCs) in physical and conceptual terms in accordance with the most recent developments in the field. The interest of (SEV(B converter designers has shifted significantly over the past decade, due to many new applications for data converters at the far ends of the frequency spectrum. Continuous-time delta-sigma A/D converters with GHz clocks, of both lowpass and bandpass types, are required for wireless applications. At the other extreme, multiplexed ADCs with very narrow (sometimes 10 Hz wide) signal bandwidths, but very high accuracy are needed in the interfaces of biomedical and environmental sensors. To reflect the changing needs of designers, the second edition includes significant new material on both theory and design techniques. New text has been added, that: . Includes insight on MASH architectures, digital-to-analog converter (DAC) mismatch and mismatch shaping. Gives information and intuition behind several new topics, including continuous-time (SEV(B ADCs, circuit design for both continuous-time and discrete-time (SEV(B ADCs, decimation and interpolation filters, and incremental ADCs. Provides information on practical design issues for industry professionals.
