Embodiment Construction
[0050] 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.
[0051] 1. Boost circuit
[0052] The booster circuit of this embodiment includes a plurality of capacitors, and outputs a voltage boosted by a so-called charge pump method.
[0053] FIG. 1 is an explanatory diagram of the working principle of the boost circuit of this embodiment. The boost circuit of this embodiment includes a first power line VL- 1 to an Mth (M is an integer greater than or equal to 4) power line VL-M. In addition, the boost circuit boosts the voltage V between the first power supply line VL-1 and the second power supply line VL-2 by (M-1) times to a boosted voltage (M-1)V, and conv...
