A digital time skew calibration technique for time-interleaved ADCs
In this paper, a digital time skew calibration technique for time-interleaved (TI) ADCs is presented. The time skew calibration for TI-ADCs in analog domain suffers from limited correction accuracy and additional jitter. And the proposed digital time skew calibration method estimates the polari...

| description |
In this paper, a digital time skew calibration
technique for time-interleaved (TI) ADCs is presented. The time
skew calibration for TI-ADCs in analog domain suffers from
limited correction accuracy and additional jitter. And the
proposed digital time skew calibration method estimates the
polarity of the time skew through correlation of adjacent
channels and corrects the time error by adopting adaptive
fractional delay filters iteratively. Simulation results show that,
in a 4-channel 1GS/s 12-bit TI-ADC system, the SFDR can be
improved to 78dB by 5-order FIR filters within a calibration
range of [-0.005/fs, +0.005/fs]. |
