An 8-bit 4.8-GS/s Four-Channel Time-Interleaved SAR ADC With Ping-Pong Comparators Using Global-Dither-Based Timing-Skew Calibration and Bit-Distribution-Based Offset Calibration

Abstract: This article presents a global-dither-based timing-skew calibration technique for time-interleaved (TI) analog-to-digital converters (ADCs). By injecting a dithered reference signal globally ...
