Abstract
A resistance/voltage converter for the generation of a voltage output signal inversely proportional to the value of a resistance to be measured comprises a reference voltage source, a first operational amplifier whose non-inverting input is connected to the reference voltage source and whose inverting input is connected to a first terminal of the resistance to be measured, whose second terminal is connected to a reference potential, a series circuit of a reference resistor and a further resistor which is switched between an output of the first operational amplifier and the first terminal of the resistance to be measured, and a voltage substraction circuit whose one side is connected to the output of the first operational amplifier and the common mode of the reference resistor and the further resistor, and whose output side generates a voltage signal referred to the reference potential.
