Charge pump down circuit and method for the same
The present invention discloses a charge pump down circuit which comprises three capacitors operating in three time phases. In the first time phase, the total of the voltages across the three capacitors is equal to an input voltage; in the second time phase, the voltage across the second capacitor is equal to the voltage across the third capacitor; in the third time phase, the difference between the voltages across the first and the second capacitors is equal to the voltage across the third capacitor, wherein the voltage across the third capacitor is the output voltage of the charge pump down circuit.
