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.
