To meet severe aeronautic environment constraints, we propose in this paper a versatile 794μW autonomous multi-power-source wireless sensor system interfacing with aeronautic-grade resistive bridge transducers and operating over a wide range of -40°C to +180°C in 180nm HT SOI technology. Compared to previously reported works, it provides robust and versatile 8Sps-1kSps sensor interface and RFID/micro wind turbine power supply scheme.
