    • A charge pump includes a first voltage input node, a second voltage input node, a voltage output node, at least a flying capacitor, an energy reserve capacitor, a first MEMS switches group controlled by a controlling signal, a second MEMS switches group controlled by the controlling signal, a third MEMS switches group controlled by the controlling signal and a forth MEMS switches group controlled by the controlling signal. The flying capacitor is connected with the first voltage input node and the second voltage input node via the first MEMS switches group. The flying capacitor is connected with the first voltage input node or the second voltage input node via the second MEMS switches group. The energy reserve capacitor is connected with the flying capacitor via the third MEMS switches group. The energy reserve capacitor is connected with the voltage output node and the second voltage input node. When a clock controls the first MEMS switches group to turn on, and the second MEMS switches group and the third MEMS switches group to turn off, the flying capacitor is charged up through the first voltage input node and the second voltage input node. When the clock controls the first MEMS switches group to turn off, and the second MEMS switches group and the third MEMS switches group to turn on, the energy reserve capacitor is charged up through the flying capacitor and the second voltage input node. Through MEMS technology, miniaturization and integration of the charge pump are achieved, and power consumption is reduced, and energy conversion efficiency is improved.
