摘要： A circuit and a method for calibrating the direct-current offset in the signal output from a signal processing unit are disclosed. The calibration circuit includes a 1-bit quantizer, a control logic unit and a digital-to-analog converter. The 1-bit quantizer is coupled to the output end of the signal processing unit for receiving and detecting a direct-current offset component in the output signal so as to obtain quantization information. The control logic unit is coupled to the 1-bit quantizer for sequentially setting one of a plurality of bits of a compensation value and updating the set bit according to the quantization information. The digital-to-analog converter is coupled to the control logic unit for compensating the direct-current offset component in the signal output from the signal processing unit according to the compensation value.
