Integral Non-Linearity in Memoryless A/D Converters

This paper investigates the statistical properties of quantization noise. In particular, a theoretical model is discussed, which evaluates the power of quantization noise introduced by a memoryless analog to digital converter (A DC) as a function of both the converted signal distribution and the ADC thresholds positioning. Expressions have also been derived to express the integral non-linearity (INL) contribution to quantization noise power as an additive term, and to evaluate such a term with a simple formula. Simulation results that validate the proposed expression are provided.
