摘要： The invention relates to an electronic device for measuring and/or controlling a property of an analyte (100). The electronic device comprises: i) an electrode (Snsr) forming an interface with the analyte (100) in which the electrode (Snsr) is immersed in operational use, the interface having an interface temperature (T), and ii) a resistive heater (Htr) being thermally and capacitively coupled to the electrode (Snsr), the resistive heater (Htr) being configured for setting the interface temperature (T) by controlling a current through the resistive heater (Htr). The resistive heater (Htr) is provided with signal integrity protection for reducing the capacitive charging of the electrode (Snsr) by the resistive heater (Htr) if the current through the resistive heater (Htr) is modulated. The invention further relates to an electrochemical sensor for determining a charged particle concentration in the analyte (100) using the thermo-potentiometric principle, the electrochemical sensor comprising such electronic device. The invention also relates to an RFID tag and a semiconductor device comprising such electrochemical sensor. The effect of the feature of the invention is that the capacitive charging effect between the resistive heater and the electrode is reduced by the signal integrity protection.
