Abstract:
A shunt regulator performs a control so as to stabilize a voltage obtained by rectifying the radio frequency signal output from an antenna unit at a prescribed voltage value. A signal extraction unit extracts the information signal from a bypass current sent by the shunt regulator for the control when the voltage fluctuates.
