摘要:
Embodiments of the invention are generally directed to compensation for common mode signal swing. An embodiment of an apparatus includes a connector for the transfer of the data, the connector including connections for a first set of one or more conductors; a receiver for the reception of data via the connector, the received data including a first signal and a second signal transmitted via the set of one or more conductors, the second signal being a common mode signal modulating the first signal, the receiver including an amplifier to amplify the received data with a positive gain; and a common mode compensation circuit to compensate for a voltage swing of the common mode signal in the amplified received data. The common mode compensation circuit is to sense the common mode signal, amplify the sensed common mode signal with a negative gain, and feed back the amplified common mode to output nodes of the receiver.
