ABSTRACT:
A voltage multiplier has first, second, and third capacitors, each having first and second plates. The multiplied output voltage is developed between the first and second plates of the third capacitor. First and second diodes are connected respectively between first plates of the first and second and the second and third diodes. A switch is connected between the supply voltage and the first plate of the first capacitor. First and second inverters are provided, each having an input, and having an output connected respectively to the second plates of the first and second capacitors. The first inverter is connected to the supply voltage to produce the supply voltage as an output of the first inverter when a low state is applied to the input of the inverter. The second inverter is connected to the first plate of the first capacitor to produce a voltage from the first capacitor as an output of the second inverter when a low state is applied to the input of the second inverter. A control signal generator has output signals connected to the switch, and inputs of the first and second inverters, the output signals being timed to open the switch and apply low states to the inputs of the first and second inverters, then to close the switch and apply high states to the inputs of the first and second inverters.
