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/tcsi.2024.3426354
Abstract: This article presents a background calibration method for timing skew in time-interleaved (TI) analog-to-digital converters (ADCs). The proposed algorithm employs fast adaptive particle swarm optimization (FAPSO) to detect the timing skews in sub-channels and compensates… read more here.
