摘要

This summary presents a fully-integrated wireless charger to achieve high efficiency with low cost and volume. The charger realizes power rectification, voltage regulation and CCCV charging in one power stage only. A bootstrapping technique is also designed for on-chip integration of the bootstrap capacitors. A chip prototype was fabricated in a standard 0.35μm CMOS process with a die area of 8mm ² . The charger achieves peak efficiency of 92.3% and 91.4% when the charging currents are 1A and 1.5A, respectively.
