ABSTRACT:
A charge pump circuit which uses a constant current from a constant current source for charging or discharging a capacitor and which obtains an output voltage by shifting a power supply voltage using a charged voltage of the charged capacitor. With this structure, a large current can be limited and generation of noise can be prevented.
