Abstract

See full text

A convenient electronic circuit in which a switch is able to be switched through electric power obtained by weak radio waves is provided. An electronic circuit includes: a power supply configured to output direct current (DC) electric power; a switch connected between the power supply and a load driven by DC electric power supplied from the power supply and configured to switch a connection state between the power supply and the load from a non-conduction state to a conduction state; an power input terminal to which electric power obtained by radio waves received by an antenna capable of receiving the radio waves is input; a DC power output terminal configured to output DC electric power, a power conversion circuit configured to convert electric power input to the power input terminal into DC electric power and output the converted electric power from the DC power output terminal; an input terminal connected to the DC power output terminal of the power conversion circuit; an output terminal connected to the switch and configured to control a connection state of the switch; and a control circuit configured to control a connection state of the switch to be in a conduction state when the power conversion circuit outputs DC electric power due to the reception of radio waves by the antenna.
