1. A thermal sensing system comprising:

  • a reference voltage generator configured to generate a non-constant first reference voltage that varies as a known first function of temperature;

    a thermal sensor configured to generate a sensor voltage that varies as a known second function of temperature; and

    a first comparator configured to receive the sensor voltage and the first reference voltage, compare the sensor voltage and the first reference voltage, and generate a first comparison output signal based on the comparison of the sensor voltage and the first reference voltage.
