Abstract
A sensor circuit comprises a sensor adapted to sense a physical quantity and to produce a sensor output signal. A sensor-offset correction block is arranged to receive a signal indicative of a supply voltage applied to the sensor circuit and to generate a compensation signal based on the signal indicative of the supply voltage and on a quantity indicative of a state of the sensor circuit. A combiner is adapted to combine the sensor output signal with the compensation signal, thereby obtaining a compensated signal.
