Abstract
A voltage regulator including a first, second, and third capacitances, first switches, and second switches. A first terminal of the first capacitance is connected to a first output. The first output is at a first output voltage. A first terminal of the second capacitance is connected to a second output. The second output is at a second output voltage. The first switches connect a first terminal of the third capacitance to a voltage supply, the first output, or the second output. The second switches connect a second terminal of the third capacitance to a reference terminal, the first output, or the second output. The first and second switches are controlled, based on the first output voltage and the second output voltage, to: adjust voltages across the first, second, and third capacitances; maintain the first output at a first predetermined voltage; and maintain the second output at a second predetermined voltage.
