  • Circuit and method for controlling a single-cell linear oxygen sensor
    Patent number: 10203299
    Abstract: A control circuit for a single-cell linear oxygen sensor having a first and a second electrical terminals on which a first voltage and respectively a second voltage are present, wherein a cell current between the first and second electrical terminals is indicative of a detected oxygen concentration, and wherein the control circuit generates a biasing voltage 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, coupled to the second electrical terminal to generate a processed voltage as a function of the cell current and based on the preset pattern; and an adder stage, coupled to the transresistance block and to the second electrical terminal, to perform a sum between the processed voltage and the second voltage, to generate the first voltage for the first electrical terminal of the linear oxygen sensor, so that the biasing voltage has the preset pattern as a function of the cell current.
