Abstract
A charge pump includes first through fifth transistors and a capacitor. The first through fourth transistors are connected in cascade and form a control circuit. The second transistor has a gate connected to its drain and hence, acts as a diode. The charge pump receives a clock signal and a supply voltage and generates an output voltage where the level of the output voltage is controlled by varying a size of the second transistor.
