Abstract
Two output voltages are generated in response to the output of a power supply. One output is referenced to the positive supply terminal V.sub.CC and the other output is referenced to the negative supply terminal V.sub.EE.. A first .DELTA.V.sub.BE reference circuit provides for the production of the pair of voltages which are temperature compensated. A second .DELTA.V.sub.BE reference circuit operates a voltage regulator which supplies the first .DELTA.V.sub.BE reference. The resulting two output voltages are temperature compensated and substantially independent of power supply voltage variations.
