Abstract
A sensor device comprises a sensor arranged to sense and convert the physical quantity into an electrical quantity and to output an electrical signal representative of the electrical quantity. A voltage limiter receives an input signal related to a supply voltage providing power to the sensor device and to output a voltage signal. The voltage signal has a limited value if the input voltage exceeds a voltage saturation threshold value. A voltage-to-current converter converts the voltage signal output by the voltage limiter to a supply current of a first value, thereby forming a first supply current state. A switch switches between the first supply current state and at least a second supply current state wherein the supply current is substantially independent of the supply voltage. Current generation means provides the supply current of the predetermined second value to form the second supply current state.
