An enhanced power plane topology using localized spiral resonator for wideband suppression of simultaneous switching noise

Using power plane applied spiral resonators, GBN and SSN can be suppressed through very wideband from 0.22 GHz to 12.5 GHz under -25 dB. Also, the designed spiral resonator is just located on the intersection between power plane and power via, and the diameter of resonator is 3 mm. Due to the localized small size of resonator, the degree of freedom for power plane design and signal integrity for guaranteed return current path are better than periodic EBG structure. Therefore, signal integrity and power integrity can be guaranteed in a low noise condition by using spiral resonator mounted power plane.
