Abstract: A digital thermometer includes a first oscillator to generate a first clock signal, wherein a period of the first clock signal remains constant in view of changes in a temperature of the apparatus and a first counter coupled to the first oscillator, the first counter to count a fixed number of cycles of the first clock signal associated with a measurement period. The digital thermometer further includes a second oscillator to generate a second clock signal, wherein a period of the second clock signal varies with changes in the temperature and a second counter coupled to the second oscillator, the second counter to generate an output representing a count of a number of cycles of the second clock signal that occur during the measurement period. In addition, the digital thermometer includes calibration circuitry coupled to the second counter, the calibration circuitry to calibrate the output of the second counter to generate a value representing the temperature of the apparatus.
