Hi,
Recently, I want to design a potentiostat to maintain the difference voltage of gas sensor electrodes, WE and RE, at constant level. The gas sensor is 3-lead electrochemical cell shown in the attachment. When I am doing the amplifier which is the basic element of potentiostat, I found it confused to model the sensor cell or the load. I have searched on the internet. There is someone using 10K ohms resistor in series with 10K ohms resistor. There is someone using M ohms resistor in series or in parallel with high value capacitor...
Anyone who have ever deal with this problem, please be kind to help me. Thanks a lot!
