Electronic circuit, electronic device, and wireless communication device

An electronic circuit comprising:

• a first switch including a first terminal connected to a power supply, a second terminal, and a control input terminal and electrically connecting the first terminal and the second terminal when a negative voltage greater than a predetermined threshold voltage with respect to a source voltage applied to the first terminal is applied to the control input terminal;
• a photovoltaic element connected in a forward direction between the power supply and the control input terminal of the first switch and applying a negative voltage greater than the threshold voltage of the first switch with respect to the source voltage to the control input terminal of the first switch using photovoltaic power which is generated by irradiation with light;
• a pull-up resistor that is connected in parallel to the photovoltaic element between the power supply and the control input terminal of the first switch;
• and
• a second switch including a first terminal connected to the control input terminal of the first switch, a second terminal supplied with a negative voltage greater than the threshold voltage of the first switch with respect to the source voltage, and a control input terminal supplied with an external control signal input from the outside of the electronic circuit and electrically connecting the first terminal and the second terminal in response to the external control signal.
