The transmitter includes a serializer, a main driver and an auxiliary driver. The serializer sequentially outputs, according to a clock signal, a first signal and a second signal as two consecutive data of a first output signal, and detects whether the first signal and the second signal are the same so as to generate a control signal. The main driver generates a second output signal according to the first output signal. The auxiliary driver is selectively switched according to the control signal, wherein the main driver and the auxiliary driver are powered by the same supply voltage.

Transmitter and signal transmitting method thereof

A post driver includes an input pair circuit, a protection circuit, a common mode sensing circuit and an amplifier. The input pair circuit outputs a first signal through a first node and outputs a second signal through a second node according to a first input signal and a second input signal. The protection circuit provides the input pair circuit with voltage protection according to multiple first bias voltages and a second bias voltage, transmits the first signal to a first load to generate a first output signal, and transmits the second signal to a second load to generate a second output signal. The common mode sensing circuit senses a level of the first node and a level of the second node to generate a feedback signal. The amplifier generates the second bias voltage according to a reference signal and the feedback signal.
