Abstract

This work proposes a one-stage correlation-based background timing-skew calibration method. It detects timing-skew errors of all channels simultaneously and relaxes the input bandwidth limitation up to the Nyquist frequency, ensuring fast and robust convergence. It enables an 11b1GS/s4-channel time-interleaved SAR ADC that achieves the best FoMs of l70.6dB and FoMw of 4. 9fJ/conv-step among all reported ADCs with f s >600MS/s.
