APPLICATION OF DIGITAL DITHER TO REDUCTION OF FEEDBACK D/A CONVERTERS INFLUENCE ON INTELLIGENT CYCLIC A/D CONVERTERS PERFORMANCE

Journal Title: Metrology and Measurement Systems - Year 2006, Vol 13, Issue 4

Abstract

The effect of termination of resolution growth, common for cyclic analogue-to-digital converters (CADCs) the, which appears after a definite (threshold) number of the conversion cycles, is investigated in the paper. The effect is caused by the finite resolution of the D/A converter (DAC) in the feedback chain. In an "intelligent" CADC (IC ADC, [1-6]), the growth of resolution can be restored by adding the digital dithering signal to the signal at the input of the feedback DAC. The dependence of the rate of restored growth of resolution on the distribution and amplitude of the dithering signal is investigated. The results of analysis are verified in advanced simulation experiments.
