摘要

设计了一种对Gen2 RFID标签的振荡器频率进行校准的方法. 该方法设计了时钟校准命令; 并给出了读写器使用时钟校准命令对标签时钟频率进行逐次逼近的校准过程. 验证结果表明,带有8位校准寄存器的电路可以把时钟偏差从50%校准到0.4%以内.

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.
