1. A method, comprising:
raising a temperature of a temperature sensor to a highest temperature of a qualification temperature range having a lowest temperature and the highest temperature;
trimming the temperature sensor such that a high temperature code generated by the temperature sensor represents an actual temperature of the temperature sensor at the highest temperature;
lowering the temperature of the temperature sensor to the lowest temperature;
determining a slope error between the high temperature code and a low temperature code generated by the temperature sensor having the lowest temperature, wherein the slope error is determined with respect to a difference between a highest temperature slope and a lowest temperature slope; and
determining a correction function that compensates for the slope error of each measured temperature code generated by the temperature sensor for temperatures across the qualification temperature range.
