A differential CML driver includes an output stage, a control circuit and a reference circuit. The output stage includes a first loading component, a second loading component, a bias component, a first metal-oxide-semiconductor (MOS) transistor and a second MOS transistor. The control circuit is coupled to the output stage and is for receiving a reference bias voltage, a first input signal and a second input signal to make one of the first and the second MOS transistor enter a cut-off region and the other of the first and the second MOS transistor enter a saturation region. The reference circuit is coupled to the output stage and the control circuit, and is for generating a common-mode voltage according to first and second output voltages of the output stage, and outputting the reference bias voltage to the control circuit according to the common-mode voltage.
