ABSTRACT:
A method for matching receiver and transmitter common-mode voltages for a high-speed direct current (DC) serial connection between the receiver and the transmitter includes measuring, at the receiver, a common-mode voltage of the transmitter. The common-mode voltage of the transmitter is an average of a voltage signal transmitted by the transmitter and received by the receiver. The method further includes comparing the common-mode voltage of the transmitter with a common-mode voltage of the receiver. The method further includes maintaining the common-mode voltage of the receiver at a first level at which the common-mode voltage of the receiver substantially matches the common-mode voltage of the transmitter.
