Abstract: In accordance with aspects of the present invention, a method and apparatus for demodulating an amplitude-modulated wireless power signal is presented. A method of receiving an amplitude modulated component of a wireless power transmission signal according to some embodiments includes receiving an input signal, wherein the input signal is based on an amplitude modulated wireless power signal; and applying an offset to the input signal to receive the amplitude modulated component. A demodulator according to some embodiments can include a first voltage-to-current converter that receives an input signal related to an amplitude modulated wireless power signal; a second voltage-to-current converter that receives an offset signal; and a summing node that adjusts a first current produced by the first voltage-to-current converter by a second current produced by the second voltage-to-current converter to produce an output signal.
