Analysis, estimation and mitigation of common mode to differential mode noise conversion in multiconductor ribbon cables

In this paper the concept of common mode to differential mode (CM-to-DM) noise conversion in Multiconductor ribbon cable has been analyzed and discussed. The ribbon cables are modeled using Multiconductor Transmission Line (MTL) approach and CM-to-DM conversion is compared to the standard 2-wire cables. Further, it has been demonstrated that the use of RF choke can substantially reduce the CM-to-DM conversion in ribbon cables.
