Abstract
A method and apparatus for providing a self-sustaining precise voltage and current feedback biasing loop. The present invention provides a circuit for initially biasing the bandgap and master bias current generator at startup. The feedback biasing loop has loop dynamics that are chosen such that the gain of the positive feedback loop is less than one so that the loop will not oscillate under normal operation after power-up.
