ABSTRACT:
A DC offset calibration apparatus is disclosed. The DC offset calibration apparatus includes an adjustment circuit and an offset calibration circuit. The adjustment circuit is utilized for receiving an input signal and an offset calibration signal, and for adjusting the input signal to generate an output signal according to the offset calibration signal. The offset calibration circuit is coupled to the output signal and to the adjustment circuit for determining the offset calibration signal according to at least the output signal and a predetermined threshold value.
