Philips K., van Roermund A.H.M. ΣΔ A-D Conversion for Signal Conditioning

Springer, 2006. — 230.The book gives an overview of the state-of-the-art in Sigma-Delta design and of the challenges for future realizations. It provides an understanding of the fundamental power efficiency of Sigma-Delta converters. In addition, it presents an analysis of the power consumption in the decimation filter. Understanding these power/performance trade-offs, it becomes clear that straight-forward digitization of a conditioning channel, i.e. exchanging analog for digital conditioning, comes at a major power penalty.The signal conditioning channel
