ABSTRACT:
For realizing a stabilized current source circuit providing a stabilized current which is insensitive to a change in the threshold voltage of a MOS transistor, a gate electrode of a first MOS transistor feeding a drain current as a constant current output is supplied with the sum of the gate-source voltage of a second MOS transistor and the potential of a stabilized voltage source.
