Patent ID: 7005903

Claim:
An apparatus, comprising: a driver to drive an output signal having a plurality of low-to-high (LH) and high-to-low (HL) signal transitions, with each of the signal transitions having a clock-to-output delay; a pre-driver coupled to the driver, the pre-driver having a first and a second stage to cooperatively generate a reshaped waveform to trigger the LH and HL signal transitions of the output signal, with the first stage generating an initial waveform and the second stage modifying the initial waveform to generate the reshaped waveform based at least in part on a difference in the clock-to-output delays of the LH and HL signal transitions; and a compensator circuit coupled to the second stage to at least contribute to provision of a feedback in a form of a control signal, the control signal being capable of controlling an adjustment period during which the second stage modifies the initial waveform.
