Abstract
A circuit and method for providing a desired resistor ratio whereby an output voltage may be derived across one of the members of the ratio pair. A voltage regulator is connected between first and second resistors of the ratio pair to provide voltage compensation partially dependent on third and fourth resistors within the regulator such that the error in each of the resistances of the desired ratio pair is cancelled by matching errors in the third and fourth resistances of the voltage regulator.
