It is required to design a conditioning circuit that interfaces a sensor to a data acquisition (DAQ) device. The sensor has 10 Ω output resistance and a maximum output voltage of 20 mV. The DAQ has an input resistance of 50 kΩ with an input range of (0-12)V. Design a conditioning circuit with three stages: Stage (1): a differential amplifier.
Stage (2): a non-inverting amplifier.
Stage (3): a voltage buffer.
It is required that stage (1) and (2) to have the same gain.

In the differential amplifier, let R1 = 10 kΩ, find R2 in (kΩ).

In the inverting amplifier. Let if R1 = 20 kΩ, find R2 in ( kΩ).
