APPARATUS AND METHOD FOR REDUCING COMMON-MODE CURRENT IN DIFFERENTIAL LINK

摘要

An output buffer is configured to receive differential input signals and to transmit differential output signals. A pre-driver is coupled to the output buffer and is configured to receive a data input signal and to generate the differential input signals for the output buffer. A feedback loop is coupled between the output buffer and the pre-driver. The feedback loop is configured to generate a feedback signal on the basis of a signal level present in the output buffer. The pre-driver is configured to receive the feedback signal generated by the feedback loop.
