Abstract: The voltage applied to the gate terminals of the charging transistors and charge-transfer transistors of two parallel pumping branches forming a charge pump is a boosted voltage generated internally and supplied in a crosswise manner. In particular, for driving the charge pump, first and second driving signals are generated respectively for the first and for the second pumping branch via a first and respectively a second driving circuit; the first and second driving signals are also supplied respectively to a first and to a second auxiliary charge pump to obtain respectively first and second voltage-boosted signals; and the first and second boosted voltages are respectively supplied to the second and to the first driving circuit.
