Abstract
A hybrid transmitter driver works in a first operation mode or a second operation mode and includes an operational amplifier, a pre-driver, a first multiplexer, a second multiplexer and an output stage driver. After receiving a signal from the first signal generator, the operational amplifier outputs a first driving signal and a third driving signal. After receiving a signal from the second signal generator, the pre-driver outputs a second driving signal and a fourth driving signal. In the first operation mode, the first multiplexer outputs the second driving signal and the second multiplexer outputs the fourth driving signal to make the output stage driver output a first transmission signal. In the second operation mode, the first multiplexer outputs the first driving signal and the second multiplexer outputs the third driving signal to make the output stage driver output a second transmission signal.
