Abstract
A comparator is provided and the comparator includes a comparing input unit and a latching unit. Wherein, the comparing input unit has a first input receiving a first comparing signal and has a second input receiving a second comparing signal. The comparing input unit drives a first intermediate node signal at a first intermediate node depending on the first comparing signal according to a first strobe signal, and the comparing input unit drives a second intermediate node signal at a second intermediate node depending on the second comparing signal according to the first strobe signal. The latching unit determines a comparing result according to at least one of the first intermediate node signal and the second intermediate node signal. In addition, the latching unit latches the comparing result according to a second strobe signal.
