Patent ID: 7863936

Claim:
A driving circuit, comprising: at least a driving unit, comprising: a first bias component, having a first node coupled to a first reference voltage, and a second node for outputting a first bias current; a second bias component, having a first node for draining a second bias current, and a second node coupled to a second reference voltage different from the first reference voltage; a first pre-emphasis unit, for receiving a first driving signal and a first pre-emphasis control signal, and generating a first pre-emphasis output signal according to the first driving signal and the first pre-emphasis control signal; a second pre-emphasis unit, for receiving a second driving signal and a second pre-emphasis control signal, and generating a second pre-emphasis signal according to the second driving signal and the second pre-emphasis control signal; and a transmitter unit, coupled to a first output port a second port of the driving circuit, for receiving the first pre-emphasis signal and the second pre-emphasis signal; a first processing unit, coupled to the first pre-emphasis unit for receiving a first input signal and generating the first driving signal and the first pre-emphasis control signal according to the first input signal; and a second processing unit, coupled to the second pre-emphasis unit for receiving a second input signal and generating the second driving signal and the second pre-emphasis control signal according to the second input signal.
