Abstract: The invention relates to a circuit arrangement for a current-controlled resistor having an enlarged linear range, using an arrangement of non-linear bipolar load elements wherein the resistance is generated between a first terminal (E) and a second terminal (F), having at least one control terminal (X) that is fed by a supply current source (I1), wherein the arrangement of the non-linear bipolar load elements comprises at least a third chain (C) comprising one or more of the load elements (DCl . . . DCi), the load elements being connected in series where there is more than one of them, and comprises a first chain (A) and a second chain (B) each comprising one or more load elements (DAl . . . DAj and DBl . . .
