A self-biased voltage-regulated current source is disclosed. The present invention includes a current source circuit for generating a constant output current; a voltage source for supplying an unstable voltage for the current source circuit; a regulating circuit for generating a regulated voltage coupled to the current source circuit; and a bias circuit, coupled to the regulating circuit, for generating a bias current to the regulating circuit and the current source circuit, where the bias current is greater than the output current of the current source circuit.
