Abstract: A sampling assembly and a sampling method are provided. A self-calibration unit controls a first switch to be turned on, to enable a first sampling signal to be input to a sampling unit. The sampling unit processes the first sampling signal to obtain a second sampling signal, and outputs the second sampling signal to the self-calibration unit. The self-calibration unit controls the first switch to be turned off, controls a second switch to be turned on, and outputs a first calibration signal to the sampling unit. The sampling unit processes the first calibration signal to obtain a second calibration signal, and outputs the second calibration signal to the self-calibration unit. The self-calibration unit determines an error signal based on the first calibration signal and the second calibration signal. The self-calibration unit obtains a calibrated third sampling signal based on the second sampling signal and the error signal.
