This book analyses different A/D-converter architectures with an emphasis on the maximum achievable power efficiency. It also provides an accessible overview of the state-of-the art in calibration techniques for Nyquist A/D converters. The calibration techniques presented are applicable to other analog-to-digital systems, such as those applied in integrated receivers. They allow implementation without introducing a speed or power penalty.
