Encrypted Tag Design for RFID Systems

Abstract

The wireless implantable RFID tag combines wireless communication technology, medical sensor technology, and data conversion technology to achieve continuous detection of body indicators. The implantable tag system includes a small signal detection circuit, a readout circuit to complete sensor data acquisition and conversion, and a digital baseband and RF front end to perform communication with an external reader. The digital baseband processor handles communication protocols, controls communication flow, configures the RF front end, and controls the sampling of human body data by the ADC, which is a key component of the implantable tag system.Based on the 13.56MHz IS015693 radio frequency identification protocol, this paper designs and implements an encrypted tag baseband. Through the analysis of the protocol and the application requirements of the tag, the system architecture of the digital baseband is formulated. Subsequently, the functional logic was verified using Cadence’s Incisive EDA tool and synthesized using Synopsys’ EDA synthesis tool Design Compiler. The simulation results show that the logic function is correct. The synthesis tool report shows that under the 0.13um process, timing closures. The setup time and hold time meet the requirements.
