ANALYSIS OF INFLUENCE OF INTERNAL CONVERTERS NONLINEARITY ON INTELLIGENT CYCLIC ADC PERFORMANCE*

The task of the paper is the presentation of a modelling approach to quantitative analysis of the influence of internal converter nonlinearities on the performance of sub-optimal intelligent cyclic A/D converters (IC ADCs) developed and analysed in works [1-5] and others. The results of investigations permit to determine requirements to the analogue elements of IC ADC architecture, first of all to an internal low-bit A/D converter (ADCIn), which is the most crucial for the design and practical implementation of IC ADC
