Radio-frequency identification tag with oscillator calibration

摘要

A method of calibrating an oscillator within a Radio-Frequency Identification (RFID) tag includes storing a plurality of calibration values within a memory structure. Each of the calibration values corresponds to a respective oscillation frequency of the oscillator. A selected calibration value is selected from the plurality of calibration values stored, according to a first selection criterion. The oscillator is then calibrated in accordance with the selected calibration value.
