ABSTRACT:
A reference voltage source with linear temperature compensation for use in a band gap voltage reference circuit. The reference voltage source comprises a voltage follower comprising a differential pair. The voltage follower is arranged in cascade with a reference circuit for supplying a compensation voltage in series with a temperature dependent reference voltage of the reference circuit. The voltage follower delivers a temperature independent output voltage between the output of the voltage follower and a reference terminal.
