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.

DOI: 10.1117/1.oe.59.3.034104
Abstract: Abstract. For a simultaneous phase-shifting interferometer (SPSI), typically four interferograms with different phase shifts are captured at different areas on the detector target by a single-shot capture method. Prior to calculating phase distribution, the region… read more here.
