Abstract
There is provided a current switching circuit that adds additional current in accordance with an intensity of output current to input current of a current mirror at a rising edge of the output current of the current mirror. The current switching circuit includes a MOS transistor outputting the additional current upon receiving ON potential at a gate terminal, and a slope of a leading edge waveform of a pulse signal providing the ON potential is controlled in accordance with the intensity of the output current.
