ABSTRACT:
The present invention provides a voltage reference level using a bipolar output transistor to provide a reference voltage on a reference output line. A control circuit is used for varying the current to the base of the output transistor in response to the load on the reference output line. In addition, the control circuit provides the reference level to the output transistor. The MOS control circuit and the bipolar output transistor are fabricated on the same chip using a BICMOS process. The voltage reference provided by the control circuit is derived from a voltage level provided by a resistor coupled between the positive voltage supply and a current source.
