DYNAMIC COMPARATOR, METHOD FOR CALIBRATING OFFSET THEREOF, AND COMPUTER STORAGE MEDIUM

Disclosed in an embodiment of the present invention are a dynamic comparator, a method for calibrating an offset thereof, and a computer storage medium. The dynamic comparator comprises: a latch and a pre-amplifier comprising a pre-amplification circuit and a calibration assist circuit, wherein the calibration assist circuit comprises a charge storage capacitor for storing offset voltage, a charge and discharge switch, a common-mode switch, a first calibration control switch and a second calibration control switch. Offset calibration is carried out by means of connecting the charge storage capacitor in series to an input end of the dynamic comparator, and by means of control of the charge and discharge switch, the common-mode switch, the first calibration control switch and the second calibration control switch. Un mode de réalisation de la présente invention concerne un comparateur dynamique, un procédé d'étalonnage d'un décalage de celui-ci, et un support de stockage informatique. Le comparateur dynamique c
