Abstract
A circuit configured to receive a first and second voltages and generate an output voltage, the circuit comprising: a first capacitor configured to charge to a voltage equal a difference between the first voltage and the output voltage; a second capacitor configured to charge to a voltage equal to a difference between the first voltage and the second voltage; and a plurality of conductive paths coupled to the first and second capacitors. In a first state, the conductive paths are configured to cause the second capacitor to charge to the voltage equal to the difference between the first voltage and the second voltage. In a second state, the conductive paths are configured to cause the second capacitor to be connected in parallel with the first capacitor to cause the first capacitor to charge to the voltage equal to the difference between the first voltage and the output voltage.
