Abstract: Disclosed are various embodiments of a current-mode line driver that may facilitate transmitting signals to a load. The current-mode line driver may comprise a common-mode current sense element that provides a signal corresponding to the common-mode output current of the line driver. A transconductance element receives the signal from the common-mode current sense element and provides a compensating current that is based at least in part on the signal. The compensating current may reduce the common-mode output current of the line driver.

Abstract: An output stage of a differential line driver generates a differential output signal. A common-mode component of the differential output signal is decoupled from the differential output signal using a common-mode voltage sense. The common-mode component of the differential output signal is provided to a capacitor that is coupled between the output stage and the common-mode voltage sense.
