A method and system calibrates a replica analog-to-digital converter. The system includes a first digital-to-analog converter to convert a digital signal into a corresponding first analog signal. A replica digital-to-analog converter generates a second analog signal based on the digital signal. The second analog signal approximately matches the first analog signal. A control module generates a calibration code based on the digital signal. A calibrating digital-to-analog converter generates a third analog signal based on the calibration code. The third analog signal substantially corresponds to the mismatch between the first analog signal and the second analog signal.
