Abstract
A circuit for measuring an unknown resistance of a resistive element comprises a sensor circuit to generate a differential voltage dependent on the resistance of the resistive element and a reference circuit to generate a differential reference voltage and a sigma-delta converter comprising a first stage, wherein a first capacitor is selectively coupled to one of the output terminals of the sensor circuit and a second capacitor is coupled to one of the output terminals of the reference circuit. The circuit generates logarithmically compressed values.
