ASIC Design of Encoding Circuit in Low Frequency Read-only RFID in Manufacturing Engineering

Article Preview

Abstract:

For the two kinds of commonly used codes in low frequency read-only RFID tag: Manchester encoding and Differential Bi-Phase encoding, we designed the corresponding encoding circuit, as shown in Fig. 5 and Fig. 10. It was fabricated by SMIC 0.35um CMOS process through full custom design method and has been successfully applied to a read-only RFID tag based on ISO/IEC 11784/5 standard. The chip testing result shows that the designed circuit can achieve ideal encoding effect, as shown in Fig. 14 and Fig. 15, which possesses the properties of high accuracy and strong anti-disturbance.
