ABSTRACT:
A current source circuit which provides an output bias current having reduced error is disclosed. The current source has reference voltage and reference current portions coupled together for providing a reference current to an amplifier means. A buffer portion is coupled to the amplifier means and to a bias current portion for substantially increasing the output impedance of the amplifier portions thereby decreasing the effect of power supply variation on the output bias current.
