Abstract:
In this work, an ultra-low-power SOI CMOS pressure sensoris presented, using P-type MOSFET strain gauges to embed an active transducer in a 1 mm² 1.5 µm-thick membrane. The system demonstrates: (i) a maximumsensitivity of 700 ppm/mbar, (ii) a precision down to 2 mbars, (iii) a power consumption less than 10 µW for the PMOStransducer.
