摘要： A method for evaluating temperature is disclosed. The method includes setting a configuration of a configurable delay line out of multiple possible configurations, and delaying a first input signal by a temperature sensitive delay line, delaying a second input signal by the configurable delay line. The configurable delay line is less sensitive to temperature than the temperature sensitive delay line. The method also includes detecting, by a phase detector, a delay difference between a delay introduced by the temperature sensitive delay line and a delay introduced by the configurable delay line, repeating the setting, delaying of the first input signal, delaying of the second input signal and detecting, until the delay difference is below a threshold, and evaluating the temperature of the temperature sensitive delay line in response to a configuration of the configurable delay line that results in the delay difference that is below the threshold.
