Claim Text:
1. A circuit comprising: a core comprising a first terminal and a second terminal and configured to generate a current proportional to absolute temperature when voltages across the first and second terminals of the core are equalized; a first amplifier comprising a first stage that includes a first PMOS transistor coupled to the first terminal and a second PMOS transistor coupled to the second terminal; a follower amplifier coupled to a terminal of the core and configured to generate a current inversely proportional to absolute temperature; a feedback stage comprising a first transistor coupled to the first terminal and having a first input gate and a second transistor coupled to the second terminal and having a second input gate, wherein an output of the first stage of the first amplifier is coupled to the first and second input gates; and an output module configured to generate a reference signal based on a reference current proportional to a sum of the current proportional to absolute temperature and the current inversely proportional to absolute temperature.
