The performance of time-interleaved analog-to-digital converters is often significantly degraded by timing mismatch errors. We develop methods for performing blind calibration of such converters, i.e., for estimating the unknown time-skew parameters and for performing signal reconstruction from these estimates. The methods are low in complexity and allow for accurate calibration in systems with large numbers of converters, provided that the skews are sufficiently small in magnitude. We also… CONTINUE READING
