US Patent Issued to STMicroelectronics Asia Pacific on July 14 for "Circuit and method of current sensing for ldo- free based rectifier in wireless charger system" (Singaporean Inventors)

ALEXANDRIA, Va., July 14 -- United States Patent no. 12,683,514, issued on July 14, was assigned to STMicroelectronics Asia Pacific Pte Ltd (Singapore).

"Circuit and method of current sensing for ldo- free based rectifier in wireless charger system" was invented by Thanh Ha Tien (Ang Mo Kio, Singapore) and Yannick Guedon (Singapore).

According to the abstract* released by the U.S. Patent & Trademark Office: "A wireless power-reception system has a bridge rectifier with two high-side and two low-side transistors, linked to input-nodes and sense-resistors. During a first phase, a control circuit activates certain transistors for rectification, producing an output voltage, while modulating a gate voltage of a non-activated low-side transisto...
