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.
