DC OFFSET CALIBRATION APPARATUS |
摘要 |
A DC offset calibration device for calibrating a DC offset of an output signal of a gain stage, the DC offset calibration device includes: a digital-to-analog converter (DAC) electrically connected to the gain stage for generating an offset current according to the DC offset of the output signal of the gain stage; and a current-to-current converter electrically connected to the DAC and the gain stage for reducing the signal scale of the offset current to generate a compensation signal so as to reduce the DC offset at the output of the gain stage.
