Abstract
A method includes post processing a plurality of temperature sensors grouped into a plurality of sets. For each set of the plurality of sets, a post-processing system coupled to corresponding temperature sensors receives a plurality output signals generated by the corresponding temperature sensors. For each set of the plurality of sets, the post-processing system computes values representing proportional to absolute temperature (PTAT) voltages and values representing internal reference voltages based on output signals generated by the corresponding temperature sensors. For each set of the plurality of sets, the post-processing system computes an average of the values representing the PTAT voltages and relative PTAT voltage variation coefficients. For each set of the plurality of sets, the post-processing system computes values representing corrected PTAT voltages using the relative PTAT voltage variation coefficients.
