A DC offset correction circuit includes a DC offset detector generating a detection voltage based on a result of a comparison of a first reference voltage and a voltage difference between signals input to the DC offset detector, a comparator comparing a second reference voltage and the detection voltage and a third reference voltage and the detection voltage and outputting first and second comparison signals, respectively, as a result of the comparisons, and an up/down counter performing an up or a down count operation in response to one of the first or second comparison signals and, as a result of the up or down count operation, outputting a signal that causes at least one control signal for canceling a DC offset in a signal input to a receiver to be generated.
