Abstract
A boosted voltage generator circuit includes a precharge voltage generator circuit and a first capacitor. The precharge voltage generator circuit receives a first DC voltage and a first power supply voltage and generates a precharge voltage having a first voltage value. The precharge voltage is inversely proportional to variations in the first power supply voltage. The first capacitor is connected between the precharge voltage node and the second power supply voltage during a first phase to be precharged to the precharge voltage and the first capacitor is connected between the boosted voltage output node and the first power supply voltage during a second phase to apply a boosted voltage at the boosted voltage output node where the boosted voltage has a voltage value being the sum of the precharge voltage and the first power supply voltage.
