  • RECTIFIER BUCK WITH EXTERNAL FET
    Publication number: 20240088719
    Abstract: A system is disclosed. The system includes a first circuit that includes a first receiver configured to receive a wireless power input, a first conductor, and operably coupled to the first receiver, and a switch network operably coupled to the first conductor configured to rectify the wireless power input and generate a rectified voltage. The first circuit further includes a first field effect transistor operably coupled to the first conductor and configured to receive a portion of the wireless power input from the first conductor and output an output voltage back to the first conductor based upon a gate input.
    Type: Application
