ABSTRACT:
A hybrid driving apparatus and a method thereof are provided. The hybrid driving apparatus includes a first driving unit, a second driving unit, and a resistor. The first driving unit has a first output end. The second driving unit has a second output end coupled to a first bonding pad. The resistor is coupled between the first output end and the first bonding pad to serve as a matching impedance. When the driving apparatus operates in a first transmission mode, the first driving unit and the second driving unit jointly drive the first bonding pad. When the driving apparatus operates in a second transmission mode, the first driving unit and the second driving unit drive the first bonding pad and a second bonding pad respectively.
