Patent ID: 7102466

Claim:
In a power distribution system including a microstrip resonator having a central stem that extends into two wings, where an external power supply is connected to the central stem that is opposite the two wings, a method of coupling out switching noise in the power distribution system, comprising: investigating a frequency response at certain points along the microstrip resonator when connected to the external power supply; identifying a fundamental mode point and other high order mode points where high noise fluctuation occurs along the microstrip resonator based on the investigated frequency response; and defining at least one external coupled resistive terminator so as to connect to at least one of the fundamental mode point or other high order mode points of the at least one microstrip resonator, and an I/O buffer, capable of switching from high to low, being connected to the at least one external coupled resistive terminator, wherein noise from the switching of the I/O buffer is coupled out from the microstrip resonator of the power distribution system by way of the at least one external coupled resistive terminator.
