The present disclosure illustrates a baseline wander compensating method adapted for compensating baseline wander induced in an Ethernet transceiver. The baseline wander compensating method comprises following steps. Firstly, an output packet is detected. Next, a detection result of the output packet and a predetermined value are compared, and a control signal is generated correspondingly. Based on the control signal, a first calibration signal or a second calibration signal is selected, and a calibrating calculation is executed for the selected one of the first calibration signal and a second calibration signal. Next, an input signal is compensated according to a baseline calibration value generated from the calibrating calculation.

The amplifier has a first positive input terminal, a second positive input terminal, and a negative input terminal to receive a start signal, a reference voltage and a feedback voltage respectively. An output terminal of the amplifier generates a driving voltage.

The power transistor generates an output voltage according to the driving voltage based on an operating power. In the voltage bypass mode, the reference voltage is equal to the operating power. A soft-start effect can be effectively achieved by the voltage regulator in the voltage bypass mode.
