Calibration Techniques for Temperature Sensors
This abstract first appeared for US patent application 18926154 titled 'Calibration Techniques for Temperature Sensors
Original Abstract Submitted
Various implementations described herein are directed to a method that acquires operating frequencies for a first set of ring oscillators disposed in a first integrated circuit, determines one or more first coefficients and a first constant for each ring oscillator in the first set, and determines a correlation between each of the first coefficients and the first constant. Also, the method may acquire a single operating frequency for each of a second set of ring oscillators in a second integrated circuit at a single pre-determined temperature so as to determine a second constant, predict one or more second coefficients for each ring oscillator in the second set based on the second constant and the correlation, and derive a temperature dependence based on the single operating frequency using the one or more second coefficients and the second constant for each of the second set of ring oscillators.
