Recent Progress on Calibration Methods of Timing Skew in Time-Interleaved ADCS.

Time interleaving has become a very common choice for increasing ADC speed. However, it is accompanied by defects such as offset, gain and time offset between the individual sub-ADCs, which can seriously degrade the performance of the overall ADC. For the elimination of gain and offset errors, the solution is relatively simple, and the calibration of the time offset is still in the exploratory stage. This paper systematically reviews several current mainstream time-interleaved ADC timing offset correction methods. At the same time, the characteristics and development trend of calibration methods are summarized. [ABSTRACT FROM AUTHOR]
