Abstract:
1. An RFID device comprising: an analog block configured to receive a radio frequency signal and to detect an operating command signal from the radio frequency signal in order to output the operating command signal; a digital block configured to receive and analyze the operating command signal and to output an operating control signal, a temperature sensor activating signal, and a temperature compensating signal; a memory block configured to receive the operating control signal, the temperature sensor activating signal, and the temperature compensating signal, the memory block comprising: wherein the temperature treating unit comprises: a temperature sensing unit configured to detect the temperature change state in the RFID device in response to the temperature sensor activating signal in order to output a reference voltage and a temperature detecting voltage; a temperature compensating unit configured to set the parameter value for temperature compensation in response to the temperature compensating signal, wherein the temperature compensating unit compares the parameter value to the reference voltage in order to output a compensating voltage; and an analog to digital converting unit configured to convert the compensating voltage and the temperature detecting voltage in response to the temperature sensor activating signal in order to output the digital code value to a data bus.
