Offset voltage correction circuit and offset voltage correction method

Abstract

The present disclosure provides an offset voltage correction circuit and an offset voltage correction method, including: a data obtaining module, configured to receive a data signal and a reference signal, and obtain a data indicator signal based on a comparison result of the reference signal and an offset data signal, the offset data signal being a data signal superimposed with an offset signal; a trimming enable module, configured to receive the data signal, the reference signal, the data indicator signal and an enable signal, obtain a theoretical indicator signal based on a comparison result of the data signal and the reference signal if the enable signal is of a high level, and generate an enable flag signal based on a comparison result of the theoretical indicator signal and the data indicator signal; and an offset correction module, configured to cancel the offset signal based on the enable flag signal.
