A metrological approach to the investigation of the quantization noise of delta-sigma ADCs
ABSTRACT A metrological approach to the analysis of the quantization noise of delta-sigma analog-to-digital converters is proposed.
The difference between the two signals at the modulator output and the ideal signals are determined. The dependence of the
quantization noise on the amplitude of the input signal and on the frequency band is obtained.

ABSTRACT: Quantization noise at the outputs of a modulator and a delta-sigma digital filter of an analog-to-digital converter is considered. Analytical and simulation modeling are used for different laws of variation of the input signal and for different types of digital filter.Measurement Techniques 56(4). · 0.29 Impact Factor
