Description
Summary:This paper introduces an adaptive blind calibration structure for the compensation of timing offsets in a two-channel time-interleaved analog-to-digital converter through Lagrange interpolation filters. By using Lagrange interpolation filters as reconstruction filters, we can exploit slight over-sampling to estimate timing offsets by using the least-mean-square algorithm. Utilizing the estimated timing offsets, we can compensate timing offset mismatches. We show the efficiency of the calibration structure by the simulations, where we compare the results with the other calibration methods from the literature.
