Abstract
A data output buffer includes a pull-up main driver outputting output data having a high level through an output pad by performing an emphasis operation according to input data, a pull-down main driver outputting the output data having a low level through the output terminal according to the input data, an active inductor controller selectively outputting an inductor activating voltage by detecting a rising or falling period of the input data, and an active inductor selectively performing a de-emphasis operation on the output terminal in response to the inductor activating voltage.
