In this paper, we measured and analyzed glass interposer power distribution network (PDN) resonance effects on a high-speed through glass via (TGV) channel for the first time. To verify the glass interposer PDN resonance effects on the TGV channel, glass interposer test vehicles were fabricated. With these test vehicles, glass interposer PDN impedance, channel loss, far-end crosstalk, and eye diagram...
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 mm×35 mm is fabricated. Also,...
In this study, a three dimensional multi-helix inductor design with a size smaller than 10mm×10mm is proposed for package-level wireless power transfer (WPT) using magnetic resonance, and the performance of an inductor-to-inductor voltage transfer ratio (VTR) of 70.1 % is presented. The effect of the power distribution network (PDN) load impedance on the VTR is studied and verified through measurement...
