Abstract
A method for performing background calibration of interleave timing errors in N order Time-Interleaved Analog to Digital Converters (TIADCs), according to which N samples of the input signal are acquired in N different phases and the time-interleave error of each phase is calculated. Then the sign of each of the time-interleave error is extracted and the errors are adjusted by adjusting the timing of erroneous phases. This process is repeated until all the errors are lower than a predefined level.
