A reference current generating circuit includes a generator that generates a reference voltage, a bias generator includes plural transistors of a different conductive types from each other and generates a first bias voltage and a second bias voltage, respectively, a first output transistor and a second output transistor of a different conductive type that outputs a current corresponds to a reference current when the first bias voltage or the second bias voltage is supplied thereto, an input-output unit that one terminal connected between the first output transistor and the second output terminal and the other terminal connected to a load, and supplies current from the first output transistor to the load or from the load to the second output transistor, and a switch that turns on/off the first and the second output transistors based on the output voltage of the input-output unit. |
