Abstract
This disclosure provides a method and apparatus for optimizing power transfer from radio-frequency (RF) rectifiers to a voltage regulator. A first RF rectifier may be configured to generate a first voltage and a second RF rectifier may be configured to generate a second voltage, where the second voltage is an open circuit output voltage. The voltage regulator may regulate the first voltage to provide power. A controller may be configured to optimize power transfer from the first RF receiver to the voltage regulator based on the first voltage and the second voltage.
