A 10-b 600-MS/s 2-Way Time-Interleaved SAR ADC With Mean Absolute Deviation-Based Background Timing-Skew Calibration

摘要

This paper presents a mean absolute deviation (MAD)-based background timing-skew calibration technique for time-interleaved (TI) ADCs. It uses a single comparator-based window detector to select input samples near the zero crossing and computes their MAD
