Zusammenfassung:The present invention generally relates to the field of electronics. More specifically, an embodiment of the present invention provides self-biased driver amplifiers for high-speed signaling interfaces. Disclosed are novel methods and apparatus for efficiently providing self-biased driver amplifiers for high-speed signaling interfaces. In an embodiment of the present invention, a self-biased amplifier driver is disclosed. The driver includes a sensing circuit to sense a presence of noise in a power supply signal. The sensing circuit may include a current source to adjust an output signal of the sensing circuit in accordance with the power supply noise. The driver may further include: an amplifier coupled to the sensing circuit to amplify the sensing circuit output signal, a pre-driver to receive a data signal, and a driver coupled to the amplifier and the pre-driver to receive an amplifier output signal and a pre-driver output signal.
