An electronic device is provided that is adapted to generate a supply voltage at an input node from a radio frequency (RF) signal. The electronic device includes a limiter coupled to the input node for limiting a supply voltage level at the input node that is generated by the received RF signal. The limiter is configured to draw a limiter current from the input node so as to limit the supply voltage level to a maximum and a magnitude of the limiter current is used for controlling a power consumption of the electronic device.
