This paper demonstrates possible design approaches for the virtual ground fence, a novel design concept for shielding power plane noise. The basic idea of a virtual ground fence is replacing discrete capacitors with quarter-wave stubs. This allows decoupling of power plane noise in the GHz spectrum. Such noise filtering is critical in a mixed-signal system, where there is switching noise generated...
In mixed-signal systems, noise coupling between different domains, such as digital and RF, can be a critical problem. Especially, the power/ground planes in packages or boards can be a major factor for noise coupling. Simultaneously switching drivers causes supply voltage fluctuations which can propagate both horizontally and vertically between the power/ground planes. The sensitive RF/analog signals...

Today; with both RF and digital devices using the same voltage source on a PCB, power filtering is needed more than ever to isolate the noise between these two types of devices for proper operation. Especially the power/ground planes in packages or boards can be a major factor for noise coupling. Simultaneously switching drivers cause supply voltage fluctuations which can propagate both horizontally...
