Abstract

A voltage booster method and circuit reduce the number of capacitors required for a voltage boost. First, a first terminal of a first auxiliary capacitor is connected to a ground line and a second terminal of the first auxiliary capacitor is connected to the supply line of an input voltage. Second, a first terminal of a second auxiliary capacitor is connected to the ground line, the first terminal of the first auxiliary capacitor is switched to the supply line of the input voltage, and the second terminal of the first auxiliary capacitor is switched and connected to a second terminal of the second auxiliary capacitor. Third, the first terminal of the second auxiliary capacitor is switched to the second terminal of the first auxiliary capacitor, and the second terminal of the second auxiliary capacitor is switched and connected to the output line.
