Abstract
A charge-pump circuit a plurality of transistor stages connected in series between a supply voltage input node and a boosted voltage output node, wherein at least one transistor stage comprises a multiple-gate transistor, which transistor comprises at least two gates, of which one is a first gate for switching the transistor on or off according to a voltage applied to the first gate, and one is an additional second gate for controlling the threshold voltage of the multiple-gate transistor, independently of the first gate, according to a control voltage applied to the second gate.
