Abstract: An apparatus, system, and method for improved power consumption and/or noise reduction in a differential input/output (I/O) buffer are provided. A circuit can include a differential signal buffer and encoding scheme quantifying and selection circuitry. The encoding scheme quantifying and selection circuitry can be configured to generate a selection code indicating a selected encoding scheme of the encoding schemes based on respective signals indicating whether each respective encoding scheme of encoding schemes has a net positive power consumption reduction in differential signals. The encoding scheme quantifying and selection circuitry can be configured to provide the selection code to an encoder.
