Identify the steps to design amplifiers to measure Ph in a chemical biosensor

- A. Select a high input impedance amplifier.
- Connect it as an inverting amplifier.
- To obtain 10mV resolution (accurately measuring changes of Ph)output with an input sensor voltage that is able to measure changes
of 0.1mV we need a gain of 101.

B. Select a high input impedance amplifier.
- Connect it as a non-inverting amplifier.
- To obtain 10mV resolution (accurately measuring changes of Ph)output with an input sensor voltage that is able to measure changes
of 0.1mV we need a gain of 100.

C. Select a low input impedance amplifier.
Connect it as a non-inverting amplifier.
- To obtain 10mV resolution (accurately measuring changes of Ph)output with an input sensor voltage that is able to measure changes
of 0.1mV we need a gain of 101.

D. Select a high input impedance amplifier.
Connect it as a non-inverting amplifier.
To obtain 1mV resolution (accurately measuring changes of Ph)output with an input sensor voltage that is able to measure changes of 0.1mV we need a gain of 101.
