CPC G01K 7/16 (2013.01) [G01K 7/021 (2013.01)] | 9 Claims |
1. A temperature sensor, comprising:
a voltage generator suitable for generating a temperature voltage that has a voltage level determined according to a temperature and a reference voltage that has a constant voltage level independent of a change in temperature;
a code generator suitable for generating an initial code based on the temperature voltage and the reference voltage; and
a code calibrator suitable for generating a calibrated code based on the initial code and a calibration factor,
wherein the calibrated code is generated by performing a gain calibration and an offset calibrations,
wherein the code generator performs the gain calibration to generate the calibrated code such that a generation range of the calibrated code corresponds to a predetermined temperature range, and
wherein the code generator performs the offset calibration to generate the calibrated code such that the calibrated code generated at a first temperature corresponds to a first target code predetermined according to the first temperature.
