Abstract: A charge pump includes: a charging unit including a first n-type transistor connected between an input terminal configured to receive an input voltage and a first node, a second n-type transistor connected between the input terminal and a second node, a first gate control element configured to control the first n-type transistor based on a first clock signal and a second gate control element configured to control the second n-type transistor based on a second clock signal having a phase opposite to the first clock signal; a first pumping capacitor including one end connected to the first node and an other end configured to receive the first clock signal; a second pumping capacitor including one end connected to the second node and an other end configured to receive the second clock signal; and an output unit.
