  "textContent": "A control circuit (10) for a single-cell linear oxygen sensor (1) having a first (11a) and a second (11b) electrical terminals on which a first voltage V s + and respectively a second voltage V s − are present, wherein a cell current (I) between the first and second electrical terminals is indicative of a detected oxygen concentration, and wherein the control circuit generates a biasing voltage (ΔV) between the first and the second electrical terminals with a preset pattern as a function of the cell current. The circuit envisages: a transresistance block (17), coupled to the second electrical terminal (11b) to generate a processed voltage (V) as a function of the cell current and based on the preset pattern; and an adder stage (16), coupled to the transresistance block and to the second electrical terminal (11b), to perform a sum between the processed voltage (V) and the second voltage V s − , to generate the first voltage V s + for the first electrical terminal (11a) of the linear oxygen sensor (1), so that the biasing voltage (ΔV) has the preset pattern as a function of the cell current (I).",
