QUANTIZATION NOISE OF THE NON-UNIFORM EXPONENTIAL TRACKING A/D CONVERSION

Dušan Agrež

Abstract

The paper presents the possibility of an adaptive A/D conversion with the non-uniform exponential tracking procedure. It has been shown that the proposed A/D conversion gives better results than the classical A/D conversion with the successive approximation procedure due to <i>b</i>-times more available sampling points. Taking into consideration only the quantization noise contribution the adaptive A/D conversion performs better results if the sampling ratio <i>s</i> is high enough.
