ABSTRACT:
A power supply circuit for supplying power to a load includes an antenna which receives electric power, a rectifier coupled to the antenna and configured to convert an alternating voltage supplied from the antenna into a direct-current voltage, a voltage step-down circuit which steps down the direct-current voltage to generate an output voltage for provision to the load, a regulator which controls a resistance connected between the output voltage and a ground voltage in parallel with the load, thereby controlling a voltage level of the output voltage.
