Abstract
A differential field plate or magnetically responsive resistors (4a, 4b) is so connected that two field plate resistors are serially connected and the common junction (J) thereof is connected to ground or, chassis; the output is taken across the free terminals of the resistance elements (4a, 4b), the resistance elements having a constant current applied thereto. The current is maintained constant for any particular temperature by a closed connecting loop including a comparator (22) comparing the voltage across any one of the field plate resistors (U.sub.A *) with a predetermined voltage (U.sub.o). Noise or disturbance voltages (U.sub.St1, U.sub.St2) are balanced out by the circuit and thus will not affect the output voltage derived across the free terminals of the field plate resistors (4a, 4b).
