This is a circuit for voltage doubler that can be connected to function as voltage doublers in order to generate output voltage. The schematic herein appears positive voltage doubling circuit using the ICL7660. This is the figure of the circuit;
In this circuit, the pump inverter switches of the ICL7660 is used to charge C1 to a voltage level of the supply voltage (V+) and the forward voltage drop (Vf) of diode D1. Voltage on C1 plus the supply voltage is applied through diode D2 to capacitor C2. And the source resistance of the output will depend on the output current.
