Abstract
An output driver includes a main output driver configured to receive data of an internal supply voltage to generate output data of an output supply voltage, and to receive the data of a ground voltage to generate the output data of the ground voltage, a pre-emphasis controller configured to detect a transition of the data from the ground voltage to the internal supply voltage to generate a first pulse signal, and to receive a pre-emphasis enable signal and the first pulse signal and generate a level-up pre-emphasis enable signal and a first level-up pulse signal of the ground voltage, a pre-emphasis pre-driver configured to generate one or more pre-emphasis pull-up control signals, and a pre-emphasis driver configured to pre-emphasize the output data based on the output data transitioning from the ground voltage to the output supply voltage.
