ABSTRACT:
An arrangement and a method for temperature compensation for a resistance (1). A resistance (1) with a controllable resistance value is compared with a reference resistance (2) which is in the form of a switched capacitor. A comparator (3) compares the two resistance values with one another. The comparator (3) takes an error signal as a basis for actuating the controllable resistance (1). This produces a thermally stable resistance. The principle can preferably be applied in transimpedance amplifiers.
