Abstract: This paper presents a time-interleaved (TI) SAR analog-to-digital converter (ADC) with a fast variance-based timing-skew calibration technique. It uses a single-comparator-based window detector (WD) to calibrate the timing skew. The WD can suppress variance estimation… read more here.

DOI: 10.1109/tcsii.2022.3188290
Abstract: This brief presents the on-chip background offset and timing-skew calibration of the 1-then-2b/cycle time-interleaved successive-approximation-register analog-to-digital converter (TI SAR ADC). For timing-skew between sub-ADC’s sampling clocks, a comparator offset-based window detector (WD) is used to… read more here.
