A background DAC error estimation in Sigma-Delta ADCs using a pseudo random noise based correlation technique


This paper presents a new approach for estimating nonidealities in unit element feedback digital-to-analog converters (DACs) of Sigma-Delta analog-to-digital converters (ΣΔ ADCs). The presented method involves a background correlation technique to determine static and dynamic device mismatches as well as a way to digitally correct a modulators… (More)
