1. A method of calibrating an oscillator frequency with an input signal in a radio frequency identification (RFID) tag device, comprising the steps of:

  • (a) receiving a calibration waveform cycle on the input signal;

    (b) incrementing a count word after each cycle of a clock signal that occurs during a length of the received calibration waveform cycle; and

    (c) adjusting the oscillator frequency based upon the count word after completion of step (b).
