An apparatus, including: a first signal receiver circuit including: a first reference voltage generator configured to generate a first reference voltage that tracks noise present in a supply voltage used to generate a first single-ended signal; and a first comparator configured to generate a first signal based on a comparison of the first single-ended signal and the first reference voltage.

Data communication apparatus with receiver employing transmitter supply voltage noise compensation

An input buffer includes a pair of input transistors and associated injection circuits. A first input transistor has a source coupled to a first voltage rail through a first current source and a gate coupled to a first wire of a multi-wire serial bus. Three or more resistors in a first injection circuit couple the wires of the serial bus to a first common node, which is coupled to the source of the first input transistor by a first capacitor. A second input transistor has a source coupled to the first voltage rail through a second current source and a gate coupled to a second wire of the serial bus. Three or more resistors in a second injection circuit couple the wires of the multi-wire serial bus to a second common node, which is coupled to the source of the second input transistor by a second capacitor.
