  • Configurable bi-directional charge pump design
    Patent number: 10170981
    Abstract: A bi-directional charge pump cell includes a p-type substrate having a main surface. A first n-well is formed in the p-type substrate that includes n+ doped regions formed in the first n? well at the main surface. A first p-well is formed in the first n? well that includes p+ doped regions formed in the first p-well at the main surface. A second n-well is formed in the first p-well that includes n+ doped regions and PMOS transistors formed at the main surface. A second p-well is formed in the first n-well that includes p+ doped regions at the main surface. A third p-well is defined in the second p-well that includes p+ doped regions and NMOS transistors at the main surface.
