  • Apparatus and method for generating temperature-indicating signal using correlated-oscillators
    Patent number: 10473530
    Abstract: A temperature sensor configured to generate a temperature-indicating signal with improved accuracy over a wide temperature range is disclosed. The temperature sensor includes a first oscillator configured to generate a first oscillating signal with a first frequency that varies with a sensed temperature and a reference parameter; a second oscillator configured to generate a second oscillating signal with a second frequency that varies with the reference parameter; and a time-to-digital converter (TDC) configured to generate a digital output indicative of the sensed temperature based on a ratio of the first frequency to the second frequency. Because the first and second frequencies depend on the reference parameter, and the temperature-indicating signal is a function of the ratio of the first and second frequencies, temperature-variation in the reference parameter cancels out in the temperature-indicating signal.
