Abstract:
A charge pump device and an operating method thereof are proposed. The charge pump device is composed of a plurality of stages of charge transfer units and an output unit that are cascaded together. Each stage of the charge transfer units includes a first node for input, a second node for output, a first circuit and a first capacitor. The first node or the second node is biased at a bias provided for the first circuit. Thereby, the first capacitors of the odd-numbered stage and the even-numbered stage of charge transfer units can respectively receive two clock signals that are mutually opposite in phase for complementary switching operating. Collocated with the switching of the output unit, an output voltage with a high negative level can be generated.
