Abstract
An apparatus comprises a band gap voltage generator circuit for generating a band gap voltage. A temperature invariant current generator is located within the band gap voltage generator circuit for generating a temperature invariant current. A temperature invariant current correction circuit is located within the band gap voltage generator circuit and adjusts the output voltage responsive to the temperature invariant current without altering temperature characteristics of the temperature invariant current.
