A voltage reference circuit is provided. The voltage reference circuit includes a first PTAT voltage generator and an amplifier. The first PTAT voltage generator is operable to generate a first PTAT voltage. The amplifier, which is coupled to the first PTAT voltage generator, comprises a second PTAT voltage generator that is complementary to the first PTAT voltage generator. The second PTAT voltage generator is operable to generate a second PTAT voltage. The amplifier is operable to generate a reference voltage based on the first PTAT voltage and the second PTAT voltage.
