  • 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.

  • Patent number: 9337808
    Abstract: A semiconductor system includes a controller and a semiconductor device. The controller receives a temperature code signal and responsively generates a mode set signal operable to adjust a level variation and a voltage variation rate of a temperature voltage signal, wherein the temperature voltage signal level varies according to temperature when a logic level combination of the temperature code signal is different from a predefined logic level combination. The semiconductor device generates the temperature voltage signal from a drivability and a resistance value set by the mode set signal. The semiconductor device generates the temperature code signal based on a comparison of the temperature voltage signal and a reference voltage signal.
