ABSTRACT:
A start-up circuit for a bias generating circuit includes a current source for providing a small charging current, and transistors for coupling the charging current to the bias generating circuit during power up to force the bias generating circuit into a steady-current state. The start-up circuit also uncouples the current source from the bias circuit after the bias generating circuit is forced into the steady-current state to prevent the charging current from affecting the operation of the bias generating circuit.
