Abstract
A novel electromagnetic bandgap (EBG)-based grid-type power distribution network (PDN), or grid-type EBG (GT-EBG), is proposed for interposer PDN. The behavior of the proposed EBG structure at cutoff frequencies is first analyzed, and a simplified circuit model is proposed to help control the bandgap behavior. Then the proposed design is realized with the integrated passive device process and validated by measurement. The measured stopband ranges from 7.5 to 15 GHz with an isolation level of -40 dB and 70% fractional bandwidth. In general, the GT-EBG consisting of different numbers of power/ground lines could be embedded in grid-type PDN for different bandgaps.
