This paper describes the use of magnetic shielding materials for improving wireless power transfer (WPT) systems efficiency by increasing the inductance of printed circuit boards (PCB) inductors. Two off-the-shelf materials are compared with a specially-made ferromagnetic disc and the inductance and quality factor results are discussed.
This paper describes the use of WEBENCH Coil Designer for generating wireless power transfer PCB inductors for low and medium power portable systems without the need of complex calculations or complex layout design.
This paper analyzes and designs inductive coupling power delivery (ICPD) system for 3-D stacked chips in SMIC 65-nm CMOS process. Two shapes of inductors, the rectangular and the octagonal inductor, are compared. Fully customized octagonal inductors with 500 μm diameter are optimized to improve power delivery efficiency. An octagonal inductor based ICPD consisting transmitter and receiver circuit...
