PCB Update - TeraOhm Input impedance test / simulate & improve.
Budget: $30 – $250 USD
I am looking for a freelancer to analyse my current schematic and PCB design. I need to verify current input impedance and if required improve the input impedance to the >1 TeraOhm range. The project requires both TeraOhm input impedance testing and PCB simulation.
Specific requirements for the new impedance value: I have a specific value in mind that I would like the freelancer to achieve. >1 TeraOhm range
I need a detailed report of the changes and simulations performed on the PCB. The documentation should provide a comprehensive overview of the modifications required. Ideally we don't want to modify the current PCB layout but hopefully only make changes to specific components to get as close as possible to the target input impedance. This means the same footprint components.
in the end the two amplification circuits are read by ADC (3.3v chip).
orp input -1500mV -> +1500 mV
pH input: -400mV -> + 400mV
See images attached of current setup.
Ideal skills and experience for this project:
- Experience in TeraOhm input impedance testing and PCB simulation
- Proficiency in analyzing and improving PCB performance
- Strong documentation and reporting skills to provide a detailed report of changes and simulations.
- Have own software for simulations.
