Abstract
This paper presents a monolithically implemented NFC bicycle tire pressure measurement system (BTPMS) with integrated antenna, on-chip capacitive pressure and temperature sensor, RFID interface for HF/NFC and EEPROM. This NFC BTPMS has been designed using a 130 nm standard CMOS process and has an active chip area of 5.76 mm2. It provides significant cost advantages and impresses with its large scale integration. The used ISO 14443 RFID communication protocol ensures compatibility with state-of-the-art NFC devices. Configuration and calibration data are stored in the integrated EEP-ROM. This battery less stand-alone system is powered wirelessly by any state-of-the-art near field communication device. Using a two-point calibration technique, various measurements have been performed and analyzed regarding accuracy, sensitivity, reproducibility, and temperature dependency. In the pressure range of 1 bar to 6 bar and for temperatures between -15°C to 55°C a ±3σ accuracy of ±0.4 bar is achieved.
