Direct and Indirect Methods of ENOB Evaluation and Analysis

Anatoliy Platonov, Łukasz Małkiewicz

Abstract

The paper presents the backgrounds of analytically grounded approach enabling strict theoretic and experimental analysis of the cyclic analogue-to-digital converters (CADC) [1,2] performance. Methods of assessment of the effective number of bits (ENOB [3,4]) and effective resolution (EFR, [5]) of these converters are considered. The analysis is based on results of works [6-8] and develops the direct approach to real ENOB values evaluation proposed in [9]. There is shown the specific for CADC and important for design and applications effect of normalisation of the output quantization noise with the growth of the number of cycles.
