A charge pumping circuit comprises: a charging pump capacitance; a charging unit; a discharging unit; a detection resistor having one terminal and the other terminal, the one terminal being connected between a first node and a second node in a second mode; a voltage source for supplying a reference voltage to the other terminal of the detection resistor; a correction unit for correcting a charging current output from the charging unit and a discharging current that is to be sunk by the discharging unit to equalize the charging current and the discharging current in the second mode, based on a difference between a voltage of the one terminal of the detection resistor and the reference voltage when the charging unit outputs the charging current to the one terminal of the detection resistor and the discharging unit sinks the discharging current from the one terminal of the detection resistor.
