Abstract
A circuit arrangement comprises a first branch comprising a resistor of variable resistance and a diode-connected bipolar transistor and a second branch comprising a resistor of fixed resistance and another diode-connected bipolar transistor. A control loop reproduces a voltage drop at the resistor of variable resistance to a voltage drop at the resistor of fixed resistance. Output terminals are connected to the bipolar transistors to supply a differential voltage. The circuit arrangement may be used as an analog frontend circuit in a gas sensor or a temperature sensor arrangement.
