Abstract: The invention concerns an electrical switching circuit with a plurality of current voltage transformers. The transfer resistance of a current voltage transformer is strongly temperature-dependent, particularly in integrated circuits. In order to suppress the drift of the transfer resistance in a plurality of current voltage transformers (Wr, W1, ..., Wn), one of the current voltage transformers is a reference current voltage transformer (Wr), the transfer resistance of which is compared with a reference resistance (Rref). The result is used to derive a criterion for adjusting the transfer resistance of all current voltage transformers (Wr, W1, ..., Wn). Application to integrated circuits with a plurality of current voltage transformers.
