Low Power Data Conversion for Sensing Applications
Modern sensing applications often require high resolution conversion without compromising power consumption. In this Chapter, the maximum out-of-band quantization noise in deltasigma converters is shown to play a key role in optimizing the performance of low power and high resolution delta-sigma analog-to-digital converters (ADCs). Two design examples will be highlighted that illustrate the use of these techniques to achieve high resolution conversion with low power consumption in deep submicron CMOS processes.
