An output driving circuit for an Ethernet transceiver is utilized for driving a load, which includes a first loading end and a second loading end. The output driving circuit includes a voltage output driver, a first resistor, a second resistor, a first current source, a second current source, a third current source and a fourth current source. The voltage output driver is utilized for providing an output voltage. The first resistor and the second resistor are utilized for modifying impedance matching with the load. When the output voltage is positive, the first current source and the second current source are turned-on, and the third current source and the fourth current source are turned-off. Whereas when the output voltage is negative, the first current source and the second current source are turned-off, and the third current source and the fourth current source are turned-on.
