1. A charge pump circuit, comprising:
a first transistor, having a first end and a second end;
a first capacitor, having a first end and a second end, wherein the second end of the first capacitor is electrically connected to the second end of the first transistor;
a second transistor, having a first end and a second end, wherein the first end of the second transistor is electrically connected to the second of the first transistor;
a second capacitor, having a first end and a second end, wherein the first end of the second capacitor is electrically connected to the second end of the second transistor; and
a reset transistor, having a first end and a second end, wherein the first end of the reset transistor is electrically connected to the first end of the second capacitor, the second end of the reset transistor receives a reset voltage, and a control end of the reset transistor receives a reset signal,
wherein the first end of the first transistor is electrically connected to a control end of the first transistor.
