1. A driving module comprising:
a voltage mode driver, electrically connected to a positive output terminal and a negative output terminal, configured to convert a positive input signal to a positive output signal at the positive output terminal, and convert a negative input signal to a negative output signal at the negative output terminal, wherein the positive input signal and the negative input signal are differential signals; and
a current mode driver, electrically connected to the voltage mode driver, comprising:
a first current source, configured to provide a first current to one of the positive output terminal and the negative output terminal;
a second current source, configured to provide a second current to one of the positive output terminal and the negative output terminal;
a third current source, configured to provide a third current to one of the positive output terminal and the negative output terminal; and
a feed-forward equalizer, electrically connected to a media access controller and the current mode driver, configured to receive a physical control signal from the media access controller and perform a pre-emphasis equalization accordingly, wherein the media access controller generates the physical control signal based on a sequence of input bits.
