  • Low noise charge pump circuit
    Patent number: 12665503
    Abstract: A charge pump circuit includes first and second capacitors, first, second, third and fourth switches, and a transistor. The first switch is coupled between a top plate of the first capacitor and a first voltage input terminal. The second switch is coupled between a bottom plate of the first capacitor and a reference voltage terminal. The third switch is coupled between the top plate of the first capacitor and a top plate of the second capacitor. The transistor and the fourth switch are coupled in series between the bottom plate of the first capacitor and a second voltage input terminal.
