Fuente: Wipo "Sensorization" A device includes a multiple analyte sensor, a transimpedance amplifier, and a differential amplifier. The multiple analyte sensor includes a first working electrode, a second working electrode, a counter electrode, and a reference electrode. Each of the first working electrode and the second working electrode is configured to receive a signal indicative of a presence of a respective analyte. The counter electrode is a sum of the received signal of each of the first working electrode and the second working electrode. The transimpedance amplifier is configured to receive a first signal of the received signals from the first working electrode and a second signal of the received signals from the second working electrode. The transimpedance amplifier converts the received first signal and the received second signal to an output including a variable bias offset. The differential amplifier is configured to subtract the variable bias offset from the output.
