Abstract (in Japanese) (See Japanese page) 
(in English) Resonances of the parasitic impedance in power distribution network (PDN) increase power current in radio frequency that leaks toward the DC power supply side of PDN.
In this report, a damper circuit was applied to reduce the resonant current. The damper circuit was composed as a parallel RL circuit that damped two type of PDN resonances, on-board and chip-package-board resonances.
The RL damper was inserted upon power traces on board and on package.
The RL damper was confirmed by circuit simulation and experimental measurement that it damps the both resonances.
And that RL damper suppress resonant peaks in the RF power current and PDN input impedance, and that it can work well in EMI reduction and PI improvement.
In addition, the effect of RL damper on immunity was also validated with wireless-communications modules being suffered of noise injection.
Immunity of the wireless-communication modules was improved by insertion of the RL damper except when frequency of injected noise was agreed to that of PDN resonance.
The RL damper is a potential way to solve EMC (emission and immunity) and PI issues.
