Abstract
The present invention refers to a charge pump system supplied by a direct voltage signal and supplying on the output terminal a voltage signal with a higher value of said direct voltage signal. The charge pump system comprising an oscillator supplied by said direct voltage signal and having two outputs in phase opposition between each other, a load storage capacitor having a first terminal connected to a first reference potential and a second terminal connected to the output terminal of the charge pump system, at least one charge section having an output charge terminal, an input supply terminal, a first side terminal and a second side terminal connected respectively to the outputs of the oscillator, a first charge transfer capacitor and a second charge transfer capacitor having respective first terminals connected to said first and second side terminals, a bridge comprising two inverters CMOS connected together with loop connection so as to form a flip-flop having inputs connected to respective second terminals of the first charge transfer capacitor and of the second charge transfer capacitor, negative supply terminals connected together to the input supply terminal and positive s…
