Abstract
A voltage multiplier circuit includes a control circuit and a first voltage multiplier stage. The control circuit receives a power supply voltage and a reference voltage and provides a first output voltage being the difference between a first selected voltage and the power supply voltage where the first selected voltage is a function of the reference voltage and is independent of variations in the power supply voltage. The first voltage multiplier stage receives the first output voltage and a clock voltage signal having a clock voltage value and provides a second output voltage being the sum of the first output voltage and the clock voltage value. When the clock voltage value is equal to the power supply voltage, the second output voltage of the first voltage multiplier stage is the first selected voltage independent of any power supply voltage variations.
