Embodiment Construction
[0066] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, the embodiment described below does not unduly limit the content of the present invention described in the claims. Furthermore, not all components described below are necessarily essential components of the present invention.
[0067] 1. Outline of the booster circuit according to the present embodiment
[0068] exist figure 1 In , the composition diagram of the boost circuit according to this embodiment is given. The boost circuit 10 outputs a boosted voltage obtained by boosting a voltage V between a system power supply voltage VDD and a ground power supply voltage VSS to an output power supply line. The output power line is connected to a device (load) using the boosted voltage.
[0069] The boost circuit 10 includes a boost voltage generating circuit 12 , a switching element SW, a charge holding circuit 14 , and a char...
