1. A wireless-power receiver comprising:

  • a resonant circuit including a power transfer element, the resonant circuit having a resonant frequency;

    a power-receiving circuit coupled to the resonant circuit; and

    a controller, coupled to the resonant circuit, configured to;

    determine a first resonant frequency of the resonant circuit corresponding to a first time;

    determine a second resonant frequency of the resonant circuit corresponding to a second time; and

    determine an offset of the power transfer element relative to a power transmitter based on the first resonant frequency and the second resonant frequency.
