  • Patent number: 10481015
    Abstract: The temperature sensor includes a voltage generator and a temperature code generator. The voltage generator includes a first temperature element having a first resistance value and a second temperature element having a second resistance value and utilizes the first and second temperature elements to generate a temperature voltage signal having a voltage level that varies according to a variation in temperature. The voltage generator generates a reference voltage signal having a substantially constant voltage level regardless of the variation in temperature. The temperature code generator compares a voltage level of the temperature voltage signal with a voltage level of the reference voltage signal to generate a plurality of temperature code signals including information on the variation in temperature based on the comparison.
