Zusammenfassung:	The disclosure relates to a negative charge pump circuit including a first capacitor; a first selector switch; a second selector switch; and a control circuit designed to, in a first phase of operation, alternately control the first and second selector switches in a first configuration in which the first and second electrodes of the first capacitor are respectively linked to the first and second nodes and in a second configuration in which the first and second electrodes of the first capacitor are respectively linked to the second and third nodes. In a second phase of operation, the control circuit forces the first selector switch to link the first electrode of the first capacitor to the second node and control the second selector switch so as to alternately link the second electrode of the first capacitor to the second and to the third node.
