ABSTRACT:
A reference current generator circuit that suppresses variations in the production of parts and attains a voltage reduction, thereby suppressing power consumption. The reference current generator circuit includes current generating circuit parts, differential amplifying circuit parts, output circuit parts that output first and second reference currents respectively, and a resistor for converting a reference current to a reference voltage. Since respective voltages are kept at the same potential, respective PMOSs are operated in a linear region by means of the differential amplifying circuit pads.
