ABSTRACT:
A voltage reference circuit for generating various selectable voltage reference values with temperature independence is disclosed wherein a band-gap voltage reference circuit portion, that produces a temperature independent band-gap voltage reference V.sub.BG output, has a cascode current mirror circuit portion coupled thereto in such manner that a selectable voltage reference V.sub.REF is output with the temperature coefficient of the selected voltage reference canceled.
