Abstract:
1. A system for reducing unwanted high frequency noise from a differential interface, the system comprising: a transmitting device; a receiving device; a first interconnect coupling the transmitting device to the receiving device, wherein a first end of the first interconnect is connected to the transmitting device and a second end of the first interconnect is connected to the receiving device; a second interconnect coupling the transmitting device to the receiving device, wherein a first end of the second interconnect is connected to the transmitting device and a second end of the second interconnect is connected to the receiving device, wherein the first interconnect and the second interconnect are parallel to one another, and wherein the first interconnect and second interconnect do not intersect with one another; and a resonator disposed in between the first interconnect and the second interconnect such that a distance between the first interconnect and the resonator is substantially equal to the distance between the resonator and the second interconnect, wherein the resonator is configured to reduce certain common-mode noise at specific frequencies from both a first signal carried by the first interconnect and a second signal carried by the second interconnect without distorting the first signal relative to the second signal or the second signal relative to the first signal.
