Classification: CPC G  H | IPC G  H

Claim 0:
1. An electronic device comprising:
a rectifier configured to output a rectified voltage to a first node by rectifying an electrical signal which is generated based on a radio frequency signal;
a voltage regulator configured to stabilize a level of the rectified voltage, generate an internal voltage, and operate in a first operation mode and a second operation mode, the first operation mode maintaining the rectified voltage, and the second operation mode stabilizing the internal voltage;
a regulator converter including a first switch configured to provide a voltage based on the rectified voltage to the voltage regulator; and
a clamp circuit configured to connect the first node to a ground according to whether the first switch is turned-on or turned-off.
