Question

# Hello, my question is as follow, I

have derived the equation (1) as below but was stock with the question of what is the sensitivity of the circuit?

Suppose you are working on circuit design for the below Atomic Force Microscope (AFM) resistive sensor in MEMS Lab. You have found that the original resistance of the sensor is 5 KΩ. The lab has a DC power supply which provides 10V, resistors (1KΩ, 5KΩ, 10KΩ, 100KΩ, 200KΩ, 1MΩ, and 2MΩ), and an Op Amplifier. Using some of these electrical components available in the lab, you want to design a circuit such that it produces an output voltage Vo which varies from 0V to 5V as the resistance of the sensor increases by 0.1 %. What is the sensitivity of the circuit, given by dVo/dR (V/Ω)? And draw the circuit you have designed.

Thank you.
