Abstract
Official abstract text for this publication.
A method and device for calibrating an oscillator and a temperature sensor in an electronic device are provided. A same temperature cycle, which includes at least two distinct temperatures, may be used to obtain data to calibrate both the oscillator and the temperature sensor. One of the distinct temperatures may comprise an ambient temperature, and a second distinct temperature may comprise a heated temperature greater than the ambient temperature. The electronic device (or a calibration device separate from the electronic device) may receive the readings from the oscillator and the temperature sensor at the two distinct temperatures in the same temperature cycle, and may determine an oscillator correction factor and a temperature sensor correction factor.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for obtaining temperature sensor output from a temperature sensor and oscillator output from an oscillator in a same temperature cycle, the method comprising: at least partly while the electronic device is at a first temperature in the same temperature cycle: receiving a first output of the temperature sensor indicative of the temperature sensor sensing the electronic device at the first temperature; sensing a first output of the oscillator indic…
