Abstract

The fundamental and practical power limits of A/D converters are identified. It will be demonstrated that oversampled A/D converters are power-efficient for the medium to high resolution range. For this type of converters, some practical low power circuit implementations are discussed. Finally, this paper will introduce the novel “analog floating point” concept for oversampled A/D. As will be demonstrated, significant power can be saved on the system level by clearly distinguishing the required SNR and the total dynamic range that has to be respected.
