Integrated rectifier and boost converter for boosting voltage received from wireless power transmission waves

An electronic device comprising:

• a wireless power receiver, comprising:
• a controller coupled with a comparator;
• a rectifier coupled to an antenna of the wireless power receiver, the rectifier being configured to rectify energy from wireless power transmission waves received by the antenna into a first voltage;
• a boost converter coupled to the rectifier, the boost converter being configured to increase the first voltage to a second voltage based on instructions from the controller;
• and
• the controller configured to control an amount of increase in voltage from the first voltage to the second voltage based on a comparison, performed by the comparator, of the first voltage with a reference voltage generated by the controller.

A method of receiving wireless power from a remote wireless power transmitter, the method comprising:

• at a wireless power receiver having a controller coupled with a comparator, an antenna, a rectifier coupled with the antenna, and a boost converter coupled with the rectifier:
• rectifying, by the rectifier, energy from wireless power transmission waves received by the antenna into a first voltage;
• increasing, by the boost converter, the first voltage to a second voltage based on instructions from the controller;
• and
• controlling, by the controller, an amount of increase in voltage from the first voltage to the second voltage based on a comparison, performed by the comparator, of the first voltage with a reference voltage generated by the controller.
