Abstract
A circuit includes a bandgap core and a bandgap amplifier. The bandgap core is capable of receiving an input voltage and generating an output voltage. A second-order temperature coefficient in the output voltage is at least partially reduced by the bandgap core while a first-order temperature coefficient in the output voltage remains substantially unchanged.
