Abstract:
A voltage supply circuit includes a booster circuit and a ripple filter circuit. The ripple filter circuit has a first resistor connected to a first output terminal at one end thereof. The ripple filter circuit also has a first switch circuit connected between the other end of the first resistor and a second output terminal. In addition, the ripple filter circuit has a second switch circuit connected between the first output terminal of the booster circuit and the first switch circuit.
