A charge pump circuit includes a sub circuit which is a pumping stage circuit or an output stage circuit. The sub circuit includes an input terminal, an output terminal, a transistor, a first capacitive device, a first diode device, and a second diode device. A transistor has a first source/drain (S/D) terminal combined with the input terminal, a second S/D terminal combined with the output terminal, and a gate terminal. The first capacitive device has a first end part combined with the gate terminal of the transistor and a second end part for receiving a first driving signal. The first diode device has a cathode combined with the second S/D terminal of the transistor and an anode combined with the gate terminal of the transistor. The second diode device has a cathode combined with the gate terminal of the transistor and an anode combined with the second S/D terminal of the transistor. So, various voltage levels between a reference ground voltage and an input supply voltage can be obtained. |
