I am building a circuit for studying neuronal signals. For this, I am using open gated FET transistors. The two input transistors of the differential pair share a common buffer/electrolyte solution and biasing for them is established using an electrode dipped in the solution. The neuron is located close one of the input transistor.
The noise due to the electrolyte ion - oxide interaction and the flicker noise degrade the SNR so badly. I want to try out chopper technique to escape from this.
Please help me with design suggestions.
Thank you,
