Abstract
A calibration method and a calibration system for sampling time adaptation in a time-interleaved ADC, a medium, and a calibrator are provided. The calibration method comprises receiving a mismatching delay of one of sub-channels in the ADC sampling a same input signal, wherein a first sub-channel among the sub-channels is a reference channel that does not require calibration, and wherein in one sampling period, the mismatching delay of each of the remaining sub-channels is estimated based on the reference channel; receiving a sampling signal of a current sub-channel to be calibrated, wherein the current sub-channel is selected by a multiplexer; and calculating a calibration slope of the sampling signal of the current sub-channel by using a linear interpolation algorithm, and obtaining a calibrated sampling signal output by the current sub-channel, based on the mismatching delay of the current sub-channel, the calibration slope and a delay calibration coefficient.
