Abstract
Disclosed herein is a wireless power reception system that utilizes a switched capacitor DC-DC voltage converter to charge a load. Current sensing circuits described herein enable the measurement of the input current to the switched capacitor DC-DC voltage converter while being relatively insensitive to temperature variation. Voltage/current sensing circuits described herein enable the selective measurement of load voltage, high side load current, and low side load current. One of the current sensing circuits may be used together with one of the voltage/current sensing circuits in a single device, or the current sensing circuits and voltage/current sensing circuits may be used separately in different devices.
