ABSTRACT:
A semiconductor booster circuit is disclosed that boosts a power-supply voltage to approximately twice the original voltage. When a reference clock signal is at the ground voltage, an inverted clock signal becomes the power-supply voltage, and the power-supply voltage is conducted from the power supply input terminal by way of a third FET transistor and stored in a first capacitor, and the stored voltage of a second capacitor is delivered from an external output terminal by way of a second FET transistor. Conversely, when the reference clock signal is at the power-supply voltage, the power-supply voltage is conducted from the power supply input terminal by way of a fourth FET transistor and stored in the second capacitor, and the stored voltage of the first capacitor is delivered from the external output terminal by way of the first FET transistor.
