DOI: 10.1109/jssc.2024.3421363
Abstract: This work proposes an autocorrelation-based background timing-skew calibration method. It uses the correlations between adjacent channels to extract timing-skew errors, which relaxes the input bandwidth limitation up to the Nyquist frequency. Moreover, the proposed technique… 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.
