A Framework for External Dynamic Compensation of AD Converters
2002 (English)In: Proceedings 7th European Workshop on ADC Modelling and Testing, 2002, 135-138 p.Conference paper (Refereed)
External calibration and compensation of analog-to-digital converters is considered. First, a dynamic correction scheme is proposed to comprise bit-masking. Next, a framework for analyzing the effects of bit-reduced table indexing is derived. This framework is finally applied in an optimization problem for bit allocation in the bit mask of the introduced correction scheme. Both the correction method and the optimization problem are exemplified using experimental ADC data. The results indicate that the considered correction scheme is superior to static schemes, and that the choice of bit mask is of great importance, motivating the analysis framework.
