  • Patent number: 7522902
    Abstract: Provided are a direct current (DC) offset compensation apparatus and a method thereof. A DC offset compensation apparatus comprises an offset detection block detecting a DC offset, an offset compensation block operating according to an output signal of the offset detection block, and an offset compensation amplifying block controlled according to an output signal of the offset compensation block. Particularly, the offset compensation block comprises a counter that counts polarities of DC offsets for a predetermined period, a controller that comprises first to fourth mode units respectively operating fast down-compensation, regular down-compensation, fast up-compensation, and regular up-compensation modes, and a control device that controls the execution of one selected among the first to fourth mode units based on a value counted by the counter, and a register storing data to control the offset compensation amplifying block based on the one mode unit determined by the controller.
