Abstract
Official abstract text for this publication.
Clock synchronization error is corrected or minimized by fitting a parabolic f(T) function to the crystal's data, and compensating for sampling period drift in an Analog to Digital Converter (ADC) at various temperatures.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for correcting clock synchronization error of a crystal oscillator by implementing temperature correction of frequency comprising the steps of: characterizing a parabolic function for the crystal oscillator by measuring an oscillation rate over a range of temperatures; recording temperature data and frequency data of the crystal oscillator during a time period requiring temperature correction to obtain at least one interval consisting of a n…
