Abstract
A system for digitizing a sampled input value includes a digital-to-analog converter for generating an output signal as a function of (1) the sampled input value, (2) a reference value, and (3) digital codes, and a multi-bit analog-to-digital converter for determining the digital codes in first, intermediate, and subsequent cycles. Dither is dynamically added to the digital-to-analog converter in the intermediate cycle. The dither is corrected for in the subsequent cycle.
