Abstract
A network driver includes first and second driver circuits and a controller which controls the driver circuits. The first driver circuit is coupled to a first node, and the first driver circuit sources first and second discrete currents to the first node and sinks first and second discrete currents from the node. The second driver circuit is coupled to a second node, and the second driver circuit sources the first and second discrete currents to the second node and sinks the first and second discrete currents from the second node. The controller controls the driver circuits so that the first driver circuit sources and the second driver circuit sinks the first current followed by the second current and so that the first driver circuit sinks and the second driver circuit sources the first current followed by the second current. Related methods are also discussed.
