Abstract :
In this paper, we present a novel design for suppressing simultaneous switching noise (SSN) propagation in high-speed PCB circuits. This design is a localized topology, where complementary double spiral resonators are etched on the metallic layer of embedded capacitance. The SSN coupling can be reduced sufficiently within an ultra-wideband from 0.26 GHz to 15 GHz under the noise mitigation margin of -60 dB. Furthermore, good signal integrity (SI) performance is achieved with small discontinuity of the return current path.
