METHODS AND CIRCUITRY TO PROVIDE COMMON MODE TRANSIENT IMMUNITY

摘要

Embodiments herein include a replica communication path and monitor circuit to provide increased common mode transient immunity. As its name suggests, the monitor circuit monitors the replica communication path and produces an adjustment signal (common mode transient adjustment signal) to cancel presence of a common mode transient signal in one or more other communication paths conveying data signals.

主权项

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; and 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 outputting the adjustment signal to the first node of the second circuit.
