Abstract: Various embodiments may provide a circuit arrangement. The circuit arrangement may include an adjustable resistor bridge configured to receive a driving signal from an electronic device, and further configured to generate one or more intermediate signals based on the driving signal. The circuit arrangement may also include an amplifier stage configured to generate an amplified signal based on the one or more intermediate signals, and a scaler configured to generate an output signal based on the amplified signal. The adjustable resistor bridge may include at least one resistor of a first resistor type having a first coefficient of resistance with respect to an environmental condition, and at least one resistor of a second resistor type having a second coefficient of resistance with respect to the environmental condition different from the first coefficient. A resistance of the first resistor type may be adjustable by a resistor stage digital control signal.
