Abstract :
The design of the analog front end proposed is one of the key elements in a passive RFID tag, including these diverse operations as a matching network for maximum power delivery, CMOS rectifier, voltage regulation, modulation and demodulation of the incident RF wave. The proposed five stages CMOS rectifier sub threshold which gives 10.8% of the power conversion efficiency and a 18.21m of read range is obtained under conditions of 900Mhz, -18.75 dBm input power and 1M DC output load. The equations for predicting the performance of the analog front end are provided and verified by both simulation results in 90nm CMOS process.
