1. A receiver comprising:

  • an antenna configured to;

    receive radio frequency (RF) power transmission waves; and

    convert the received RF power transmissions waves into an alternating current; and

    a synchronous rectifier, coupled to the antenna, configured to synchronously rectify the alternating current into a direct current, wherein the synchronous rectifier includes;

    a first diode configured to receive a first portion of the alternating current that has a positive polarity;

    a second diode configured to receive a second portion of the alternating current that has a negative polarity;

    a first transistor coupled to the first diode; and

    a second transistor coupled to the second diode.
