ABSTRACT:
Methods and apparatus may operate to use multiple oscillators to generate a demodulator clock signal and a modulator clock signal within a radio-frequency identification (RFID) circuit. The demodulator clock signal may be generated from a radio-frequency signal received at the RFID circuit. A modulator clock signal may be generated using a calibration value stored in a non-volatile memory.
