Wireless Power Distribution Network for 3D Package using Magnetic Field Resonance
In this paper, a wireless power transfer (WPT) scheme using magnetic field resonances for 3D packages is proposed and a wireless power distribution network (PDN) in a WPT system is analyzed in terms of the simultaneous switching noise (SSN). For analyzing the wireless PDN impedance characteristic and the power efficiency, a ball grid array (BGA) package with a size of 35 mmx35 mm is fabricated. Also, a new schematic of the wire PDN is defined to analyze a WPT system applied to the WPT system in terms of SSN. The impedance (Z11) characteristics between the interconnection-based hierarchical PDN structure and the hierarchical PDN based on the proposed WPT scheme are compared and analyzed. The package-level WPT system proposed in this study represents excellent wireless PDN impedance characteristics in decreasing the power noise occurred in a 3D package.
