| Abstract(in English) | RL snubber had been proposed as a method to damp the LC resonance over a power distribution network for digital integrated circuits (ICs). The RL snubber was investigated whether the effect of PDN resonance damping depends on locations at which it was implemented in the surface of a printed circuit board. In this study, RL snubbers was implemented at two locations near and apart from a digital IC on a test board. For each of the two implemented locations, RL snubber was optimized in terms of its component parameters, resistance and inductance. The optimized RL snubbers were applied to damp the PDN resonance reducing the RF power current. It was confirmed according to both circuit simulations and measurements that the two RL snubbers reduced RF power current equally around the resonant frequency, independent on their implemented locations. This means that the RL snubber involves a flexibility of implementation location on a printed circuit board. When you apply an RL snubber to your printed circuit board, you can place it in any room flexibly in response to your design. |
