该论文提出了一种完全集成的6W无线功率接收器，工作在6.78MHz磁共振耦合频段，适用于便携电子设备和医疗植入物等应用。解决了宽范围功率传输和多设备同时充电的问题，符合A4WP标准。
of Technology, Atlanta, GA 1 3 Wireless power transfer (WPT) systems are becoming ubiquitous with applications in powering medical implants and a range of portable consumer electronic devices such as smart phones and wearable devices. Wireless power transferring methods can be classified into two types: inductive and resonant. For the resonant type, wider-range power transfer is possible, and multiple devices with different power requirements can be charged at the same time. The Alliance for Wireless Power (A4WP) has chosen the 6.78MHz ISM band as the power-transfer frequency [1]. At 6.78MHz, the associated switching loss is an order of magnitude larger than that in a typical wireless receiver based on an inductive coupling, with a carrier frequency of around 200kHz. Besides the two
