Abstract
A bandgap voltage reference circuit having temperature curvature correction, comprises a bandgap voltage source configured to generate an output voltage, and a novel curvature correction circuit. The correction circuit is responsive to the bandgap voltage source output voltage and connected to apply a curvature correction signal to the bandgap voltage source to compensate for output voltage temperature dependency of the bandgap voltage source.
