The specific architecture of an A/D converter influences the code probability distributions that result from random input noise. In particular, the ouput codes of successive approximation A/D converters have a spiked distribution, and its variance is half that of the corresponding input noise. In addition, the distribution has a small bias. These and other related results are derived, and are qualitatively supported by measurement data on a real 16-bit A/D converter.
