Abstract

A clock calibration method for RFID tag is proposed, including an EPC Gen2 compatible clock calibration command, an on-tag current switch network,and a reader-tag successive approximation calibration process. The results show that the method calibrates 50% fabrication error to 0.4% with 8-bit calibration registers.
