Claim:
1. An apparatus comprising: a first communication path coupling a first node of a first circuit to a first node of a second circuit, the first communication path conveying a communication signal to the second circuit; a second communication path coupling a second node of the first circuit to a second node of the second circuit, both the first communication path and the second communication path exposed to a common mode transient; a monitor circuit that monitors the second node of the second circuit, the monitor circuit generating an adjustment signal based on the common mode transient, the monitor circuit monitoring current received over the second communication path to generate the adjustment signal, the monitor circuit outputting the adjustment signal to the first node of the second circuit; and wherein the adjustment signal is a drive current whose magnitude substantially matches a magnitude of the current received over the second communication path.
