Abstract
Aspects of a method and system for compensating temperature readings from a temperature sensing crystal integrated circuit are provided. In this regard, a temperature indication and calibration voltages from a temperature sensing crystal integrated circuit (TSCIC) may be digitized and the digital signals may be utilized to calculate a compensated temperature indication. Data derived from a memory integrated within the TSCIC may be retrieved based on the compensated temperature indication. The retrieved data may be utilized to control operation of one or more circuits. The compensated temperature indication may be calculated by removing a gain error and/or offset error from the digitized temperature indication. The compensated temperature indication may be utilized as an index for a data table. The compensated temperature indication may be a normalized compensated temperature indication. The calibration voltages may include a minimum voltage and/or a maximum voltage that the TSCIC is operable to output.
