Multiplexing circuit, output stage, and semiconductor device

An output stage of a semiconductor device, coupled to an output port of the semiconductor device for receiving a transmission line and comprising:

• a multiplexing circuit, comprising:
• a first type transistor;
• a second type transistor, coupled to the first type transistor, wherein the first type transistor is different from the second type transistor;
• and
• an impedance circuit, arranged to provide an impedance between a gate terminal of the first type transistor and the second type transistor;
• an input circuit arranged to receive a first clock signal and a second clock signal, including a sub-output terminal, and the sub-output terminal is connected to a gate terminal of the second type transistor;
• and
• a driving circuit, coupled between the multiplexing circuit and the output port.
