Abstract
A reference voltage generator that does not require a start-up circuit or a feedback loop generates a proportional-to-absolute-temperature (PTAT) output voltage based on two complementary-to-absolute-temperature (CTAT) currents. The reference voltage generator provides a reference voltage that is a sum of the PTAT output voltage and a CTAT voltage.
