1. A sampling assembly, wherein the sampling assembly comprises:
a self-calibration unit;
a sampling unit;
a first switch, wherein the first switch enables a first sampling signal to be input to the sampling unit; and
a second switch;
wherein the self-calibration unit is configured to control the first switch to enable the first sampling signal to be input to the sampling unit;
wherein the sampling unit is configured to:
process the first sampling signal to obtain a second sampling signal; and
output the second sampling signal to the self-calibration unit;
wherein the self-calibration unit is further configured to:
control the first switch to be turned off;
control the second switch to be turned on; and
output a first calibration signal to the sampling unit;
wherein the sampling unit is further configured to:
obtain a second calibration signal by processing the first calibration signal; and
output the second calibration signal to the self-calibration unit;
wherein the self-calibration unit is further configured to:
determine an error signal based on the first calibration signal and the second calibration signal; and
wherein the self-calibration unit is further configured to:
obtain a calibrated third sampling signal based on the second sampling signal and the error signal.
