Abstract
In this work, flexible corrugated interconnection and Fan-Out Wafer-Level packaging platform called FlexTrate™ is used to fabricate a thin film, flexible, magnetic resonant wireless recharging module for charging commercial Li-ion battery at an output of 3.3 V constant voltage. A power management IC (LDO bare die LDBL20) for voltage regulation, a fullwave bridge rectifier, a Si-DT capacitor dies for antenna matching. The coil antenna is also fabricated on the PDMS substrate using standard BEOL Cu metallization. The designed power module can deliver 3.9 mW regulated power.
