Abstract
A digital background calibration technique to estimate the sample-time error (timing-skew) in timeinterleaved ADCs is presented. Compared to the state-ofthe- art, this technique requires a simpler digital block and, hence, a lower power dissipation. The proposed technique detects timing skew for each channel by means of finding zero-crossing samples with respect to a reference comparator. Simulation results show that it can effectively correct timing errors for any type of input signal up to Nyquist, and achieves a high convergence speed with a very low computational complexity.
