Abstract
A charge pump circuit including a number of pull-up stages connected in parallel with one another between a reference potential line and an output line. Each stage includes a capacitor having a first terminal connected to a charging and discharging node, and a second terminal connected to a pull-up node for switching between a first charging operating phase and a second charge transferring operating phase. The charging and discharging node is connected to the supply line via a charging transistor having a control terminal connected to a high-voltage bias node formed by the adjacent stage in the opposite operating phase, for charging the capacitor substantially up to the supply voltage.
