Pre-emphasis circuit and differential current signaling system having the same
Provided is a pre-emphasis circuit which transmits a pre-emphasis output current to an output node of an output driver in response to first to fourth pre-emphasis control signals generated by a logical operation on differential input signals. The pre-emphasis circuit includes: a first pre-emphasis circuit driven in a range between a first voltage and a second voltage and configured to generate a first pre-emphasis output current in response to the first and second pre-emphasis control signals and output the generated first pre-emphasis output current to a first output node of the output driver; and a second pre-emphasis circuit driven in the range between the first voltage and the second voltage and configured to generate a second pre-emphasis output current in response to the third and fourth pre-emphasis control signals and output the generated second pre-emphasis output current to a second output node of the output driver.
