Simple dc to dc voltage multipliers using 555 timer, NOT gate and silicon diode.
---> 1st capacitor charge up to supply voltage.
---->And other capacitor voltage will increase gradually with equation ( previous cap voltage + timer output voltage).
----> Last capacitor is the polarized capacitor for storing energy.
----> There is 13 ceramic cap and 1 polarized cap and 14 silicon doide.
----> Output voltage = Vsupply +( 12cap* timer out voltage) - (14 diode * 0.7volt)
