A pre-emphasis circuit and methods are provided. The circuit includes a first amplifier and a second amplifier. The first amplifier is operable to amplify a signal using a first amplifier current, and the second amplifier is operable to amplify a delayed version of the signal using a second amplifier current. The pre-emphasis circuit further includes a logic circuit operable to change a pre-emphasis ratio of the pre-emphasis circuit including switching off one or more of first driver cells of the first amplifier and switching on a corresponding one or more of second driver cells of the second amplifier, such that a total current consumption of the first amplifier and the second amplifier remains substantially constant.
