Abstract
Aspects of a method and system for compensating temperature readings from a temperature sensing crystal integrated circuit are provided. An electronic device may digitize a temperature indication received from a temperature sensing circuit, digitize one or more calibration voltages received from said temperature sensing circuit, and calculate a compensated temperature indication utilizing the digitized calibration voltage(s), and the digitized temperature indication, and data from a table that characterizes behavior of the temperature sensing circuit as a function of temperature. One or more circuits in the electronic device may be controlled based on the compensated temperature indication. The compensated temperature indication may compensate for a gain error and/or offset error of a digital to analog converter that digitizes the temperature indication and the calibration voltage(s). There may be two calibration voltages.
