摘要：According to the charge pump circuit, a constant current charging anddischarging circuit using follower circuits is interposed at current paths in charging anddischarging a capacitor for stepping up. Transistors of the follower circuits arealternately 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 incooperation with resistors or the like.
