Samsung patents method to fix timing errors caused by temperature changes
Samsung describes a circuit that monitors the temperature of a crystal oscillator to detect timing shifts in digital signals. It generates data about these shifts and stores it in memory to help correct the signal's frequency.
In the filing’s own words
A system and a method are disclosed for frequency-drift correction. The method includes receiving, by a sample-correction interface circuit, a digitized signal, receiving, by the sample-correction interface circuit, information associated with a crystal temperature, generating, by the sample-correction interface circuit, an uncorrected sample based on the digitized signal, generating, by the sample-correction interface circuit, crystal drift data associated with the digitized signal and the information associated with the crystal temperature, and sending, by the sample-correction interface circuit, at least one of the uncorrected sample or the crystal drift data to a memory.
What exactly they claim (claim 1)
1. A method for frequency-drift correction, the method comprising: receiving, by a sample-correction interface circuit, a digitized signal; receiving, by the sample-correction interface circuit, information associated with a crystal temperature; generating, by the sample-correction interface circuit, an uncorrected sample based on the digitized signal; generating, by the sample-correction interface circuit, crystal drift data associated with the digitized signal and the information associated with the crystal temperature; and sending, by the sample-correction interface circuit, at least one of the uncorrected sample or the crystal drift data to a memory.
