A transmitter for supplying a large current upon phase change of an output voltage is disclosed. The transmitter includes a first amplifying unit including a first amplifier including first NMOS and PMOS transistors connected by a common source thereof, and a second amplifier including a second PMOS and NMOS transistors connected by a common drain thereof while being connected with the first amplifier in parallel, a second amplifying unit including a third amplifier including third NMOS and PMOS transistors connected by a common source thereof, and a fourth amplifier including fourth PMOS and NMOS transistors connected by a common drain thereof while being connected with the third amplifier in parallel, and differential output nodes including a positive node connected to an output stage of the first amplifying unit, to which the common source of the first amplifier and the common drain of the second amplifier are connected, and a negative node connected to an output stage of the second amplifying unit, to which the common source of the third amplifier and the common drain of the fourth amplifier are connected.
