ABSTRACT:
In a circuit for a sensor the output signal of which is dependent not only on the variable to be determined but also on the temperature, an amplifier having a temperture-dependent amplification factor is connected to the output of the sensor, and the output of the amplifier is connected to an adder circuit to which a temperature-dependent voltage can be fed. The amplifier is preferably a differential amplifier within the feedback branch of which a temperature-dependent resistor is inserted. The adder circuit is preferably formed by another differential amplifier to the inputs of which the output signal of the differential amplifier with temperature-dependent amplification, the temperature-dependent voltage and a substantially temperature-independent voltage can be fed via resistors.
