Abstract :
The performance of time-interleaved ADCs (TI-ADCs) mainly suffers from timing mismatches. We introduce an accurate blind timing mismatch identification for bandlimited, oversampled input signals, which is based on a frequency relation between the input signal and the sampled output signal and the fact that timing mismatches are generally small compared to the sampling period. We provide a detailed derivation of the method and discuss questions of implementation and complexity. Finally, we show the potential of the method through numerical simulations
