Abstract: An output buffer generates 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 having a first and a second stage generates 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 feedback reflective of a difference in the clock-to-output delays of the LH and HL signal transitions.
