Abstract
A voltage multiplier and capacitive isolation power supply using capacitors, diodes and first and second clock signals that are out-of-phase with respect to each other. When the first clock signal is high and the second clock signal is low, a capacitor in a first stage transfers charge to a capacitor in a second stage. When the first clock signal is low and the second clock signal is high, the capacitor in the second stage transfers charge to an output capacitor, and the capacitor in the first stage is recharged via a feedback diode between a capacitor connected to a ground potential and the capacitor in the first stage. Additionally, the capacitors in each of the stages provide an isolation function for the power supply.
