<p>A voltage booster device may include a plurality of multiplication stages arranged in a sequence so that an input terminal of each multiplication stage, with the exception of a first multiplication stage, is connected to an output terminal of a previous multiplication stage. Each multiplication stage may include pumping circuitry for accumulating an electric charge proportional to a pump voltage value of the multiplication stage. Each multiplication stage may also include a phase signal generating circuit for switching the multiplication stages between a transfer phase and a maintaining phase. In at least one of the stages, the pumping circuitry may include at least two series connected charge accumulators. A terminal may be shared between the charge accumulators and may be connected through biasing circuitry to an output terminal of a previous multiplication stage for forcing the charge accumulators within a threshold potential drop value.</p> |
