Abstract
A sensor circuit for measuring a physical or chemical quantity comprises a capacitive sensor. A sense and a base electrode of the sensor form a capacitive element with a capacity depending on the quantity. A common electrode of the sensor forms a first and a second parasitic capacitance together with the sense and the base electrode, respectively. The sensor circuit is adapted to store a charge on the capacitive element and to read out the stored charge via the sense electrode. A buffer element is connected between the sense electrode and the common electrode and adapted to drive the common electrode at a voltage applied to the sense electrode.
