Abstract

A transmission driver includes a pulse generator and a current mode logic driver. The pulse generator is configured to generate and output a first pulse signal by synchronizing at a falling edge time point of a first input signal, and generate and output a second pulse signal by synchronizing at a falling edge time point of a second input signal. The current mode logic driver is configured to output a pre-emphasis signal to which pre-emphasis technique has been applied by changing a first load resistance value and a second load resistance value based on the first pulse signal and the second pulse signal, respectively.
