Abstract:
1. A voltage supply circuit comprising: a first holding element with a first end and a second end that supplies a voltage held between the first end and the second end to a load, the second end being connected to a ground; a second holding element with a first end and a second end, the first end of the second holding element being electrically connected to the first end of the first holding element; a charging circuit that, during a first mode, charges the second holding element with a voltage higher than the voltage to be supplied to the load; and a potential adjusting circuit that, during a second mode that is separate from the first mode, shifts a potential at the second end of the second holding element towards a potential at the first end of the first holding element according to the voltage held by the first holding element or the second holding element, wherein the potential adjusting circuit includes:
