- There is provided a digital Direct Current (DC) offset correction method and device. The device includes a digital-analog converter charging a load capacitor according to an input code value and generating an initial voltage value of the load capacitor; a comparator comparing an output DC offset value of a discrete-time amplifier and filter on the basis of the initial voltage value with a preset output DC offset value when the discrete-time amplifier and filter and the load capacitor are connected to each other; and a controller changing the input code value of the digital-analog converter according to comparison result of the comparator.
