Abstract

A switched capacitor network includes a first capacitor being charged and discharged in alternation by a first switch device and being connected to a first voltage source for charging. A second capacitor is charged and discharged by the second switch device in synchronism with the first capacitor and is switched between the first voltage source and the second voltage source for charging. A product of the capacitance of the first capacitor and the voltage of the first voltage source is equal to a product of the capacitance of the second capacitor and a voltage difference between the two voltage sources. A product of the capacitance of the first capacitor and a contact resistance of the first switch device in a supply line path thereof, is equal to a product of the capacitance of the second capacitor and a sum of an internal resistance of the second voltage source and a contact resistance of the second switch device in a supply line path of the second capacitor.
