1. An RFID circuit for use within an RFID tag, the circuit including: first clock generation circuitry to generate a modulator clock signal within the RFID circuit, the modulator clock signal being generated utilizing a first calibration value stored within a non-volatile memory associated with the RFID tag; and second clock generation circuitry to generate a demodulator clock signal within the RFID circuit, the demodulator clock signal being recovered from a radio-frequency signal received at the RFID tag.
