ABSTRACT:
A charge pump system is provided that includes at least one first pump for generating a first working voltage, a second pump for generating a second working voltage, and a third pump for generating a third working voltage. The first pump is connected to an internal supply voltage reference that can having a limited value, and has an output terminal connected to the second and third pumps so as to supplying them with the first working voltage as their supply voltage. A method is also provided for managing the generation of voltages to be used with such a charge pump system.
