Abstract: A MEMS gyroscope, wherein a suspended mass is mobile with respect to a supporting structure. The mobile mass is affected by quadrature error caused by a quadrature moment; a driving structure is coupled to the suspended mass for controlling the movement of the mobile mass in a driving direction at a driving frequency. Motion-sensing electrodes, coupled to the mobile mass, detect the movement of the mobile mass in the sensing direction and quadrature-compensation electrodes are coupled to the mobile mass to generate a compensation moment opposite to the quadrature moment. The gyroscope is configured to bias the quadrature-compensation electrodes with a compensation voltage so that the difference between the resonance frequency of the mobile mass and the driving frequency has a preset frequency-mismatch value.

Abstract: A gas measurement device measures gas using a gas sensor including a sense resistance exposed to the gas and a reference resistance not exposed to the gas. The gas measurement device applies a first current value and a second current value to the sensor. A detector functions to detect a first resistance variation and a second resistance variation of the sense resistance exposed to the gas with respect to the reference resistance as a function of the first current value and the second current value, respectively. The resistance variation dependent on relative humidity is then determined as a function of the first and second resistance variations and a first constant. The resistance variation dependent on gas content is then determined as a function of the first and second resistance variations and a second (different) constant.
