ABSTRACT:
According to the charge pump circuit, a constant current charging and discharging circuit using follower circuits is interposed at current paths in charging and discharging a capacitor for stepping up. Transistors of the follower circuits are alternately made ON in accordance with a clock signal inputted from a signal input portion for switching to connect the capacitor for stepping up and restricting a current in cooperation with resistors or the like.
