Correction device

A device, comprising:

• a detection circuit configured to detect an initial logic state of an input signal, and configured to generate, in response to the initial logic state, a first signal having a first logic state;
• a correction circuit configured to compare the first signal having the first logic state with a second signal having a second logic state received by the correction circuit, and the correction circuit being configured to generate an enable signal according to the comparison, wherein the second logic state of the second signal has the same logic state as the initial logic state of the input signal;
• and
• an adjustment circuit configured to be enabled by the enable signal when the first logic state of the first signal is different from the second logic state of the second signal, to generate an adjustment signal to the detection circuit,
• wherein the detection circuit is further configured to be adjusted according to the adjustment signal, to generate an adjusted first signal.
