DOI: 10.1049/el.2020.0425
Abstract: A background calibration technique for time-interleaved analogue-to-digital converter (TIADC) over Sub-Nyquist frequency timing mismatch is proposed. When the input signal only satisfies the Nyquist sampling theorem of the overall TIADC rather than sub-ADC, both directions… read more here.

DOI: 10.1109/tcsi.2022.3163431
Abstract: This paper proposes a novel all-digital background calibration of timing mismatch for a time-interleaved analog-to-digital converter (TIADC). For two different calibration strategies, the absolute calibration and the relative calibration, the inductive expressions of modulation matrices… read more here.

DOI: 10.1109/tvlsi.2023.3235393
Abstract: This brief proposes a timing mismatch calibration for time-interleaved analog-to-digital converters (TI ADCs) with the novel parallel correlation derivative (PCD) technique and two-stage analog–digital hybrid compensation. The PCD technique could solve the frequency-relevant problem caused… read more here.
