Digital Timing Error Calibration of Time-Interleaved ADC with Low Sample Rate

This work suggests a novel procedure of calibrating timing mismatch of time-interleaved Analog-to-Digital conversion. Here, the timing mismatch calibration and compensation are both performed digitally. The proposed method is simple and it is able to find timing errors below the Nyquist rate of the individual analog-to-digital converter. Moreover, the method can be easily modified for digital gain error calibration.
