Electronic device and power management method
First Claim
1. An electronic device comprising:
- a first power extraction unit configured to extract a first amount of power from an RF field present on an RF antenna and to provide said first amount of power to one or more circuits of the electronic device;
a second power extraction unit configured to extract a second amount of power from the RF field and to provide said second amount of power to an output of the electronic device;
a control unit configured to control the second amount of power provided to said output, wherein the control unit is configured to control the second amount of power provided to the output in dependence on the strength of the RF field.
