Abstract
In a charge-pump device, a charge-pump circuit has an input, which is connected to a supply line and receives a supply voltage, and an output; in the charge-pump circuit a first elementary stage defines a first transfer node and a second transfer node that can be connected respectively to the input and to the output, and has at least one first phase input. In addition, in the first elementary stage a first switching element is arranged between the first transfer node and the second transfer node, has a control terminal receiving a control signal, and is closed during a charge-transfer interval; and first charge-storage means are connected between the control terminal and the first phase input. In the first elementary stage, a voltage-booster stage has an input connected to the first phase input of the first elementary stage, and an output connected to the first charge-storage means and supplies a boosted phase signal; in particular, the voltage-booster stage is operative during the charge-transfer interval.
