Abstract
An electronic circuit includes: a load; a load switch that switches a connection state between a power source and the load to any one of a conductive state and a non-conductive state; a first power conversion circuit that outputs first DC power based on first power obtained by a first radio wave received by a first antenna; a second power conversion circuit that outputs second DC power based on second power obtained by a second radio wave received by a second antenna; and a control circuit that has a first input terminal, a second input terminal, and an output terminal of turning the load switch into a conductive state when the first DC power is input to the first input terminal and turning the load switch into a non-conductive state when the second DC power is input to the second input terminal. The load switch is controlled to maintain a conductive state even when the second radio wave is received by the second antenna in a conductive state.
