More Information
Summary:A novel UHF RFID communication link rate adjustment strategy based on the coprime factor algorithm was proposed, and chip-level physical implementation was performed using 0.18um CMOS process. The test result shows that the new reverse link bit rate adjustment scheme not only controls the BLF violation within 5%, effectively avoids electromagnetic interference. The implementation reduces the design complexity of the chip baseband circuit where reverse link realization clock is 640KHz, jitter is 0.8ns and power consumption is 140nA.
