Modern day CMOS processes are characterized by voltage scaling and geometry scaling. Geometry scaling helps reduce gate delays, thereby aiding in the design of data converters which use time based processing. Another artifact of geometry scaling is the increase in complexity of digital circuitry available on traditional analog ICs, as...
An analysis of the statistics of multi-stage (pipeline, SAR and algorithmic) ADCs with redundancy is performed and the ability to achieve an extra 6dB of resolution in ADCs with half-bit redundancy is shown due to probability density function (PDF) residue shaping. This paper classifies redundancy techniques to show that only...
