Development of low-voltage fluid-based inclination sensor integrated with CMOS circuitry on ceramic substrate
説明
A low-voltage and fluid-based inclination sensor has been developed with one-side electrode structure at the supply voltage of 1.3 V which used in most digital circuitry. The consumption current of the inclination sensor was decreased from 250 muA at Vdd 3.3 V to 38 muA at Vdd 1.3 V by replacing an operational amplifier to an inverter amplifier in the capacitance detection circuitry of the sensor. The sensor and detection circuitry was integrated on one ceramic substrate. The sensitivity, response time and resolution of sensor were 7 mV/deg, 0.7 s and 0.75 deg respectively at the supply voltage of 1.3 V.
