RFID sensor device based on pulse-processing
Abstract:
A radio frequency identification device having sensing elements incorporated in the clock generators of its tags, which generate a leading code and an identification code. In the interrogator, the leading code is detected and its pulse width is measured for calculating sensing values and the baud rate in receiving the identification code. No analog to digital converter is needed in digitizing sensing values and only discrete signals exist in sensing signal generation and communication. The tag device is insensitive to variations in its power supply voltage obtained from a continuous wave RF carrier.
