Use of 4 floating current sources

Click For Summary
The discussion focuses on the implementation of four floating current sources for resistive sensors, aiming to achieve an output voltage that is linearly proportional to the sensor resistance. The user expresses confusion regarding the absence of a ground reference in the setup, which complicates the circuit design. They mention aligning the current sources vertically and connecting the reference voltage (Vref) to a single point. A question arises about the meaning of a horizontal line at the bottom end of the resistor (Rs), indicating a need for clarification on circuit symbols. Overall, the conversation highlights the challenges of working with floating current sources in sensor applications.

Homework Statement


I have 4 resistive sensors thus I need to tie 4 floating current sources. Floating current source will give me output voltage linear to the resistance of a sensor. I know it is not the best solution but it is good enough.

Homework Equations


None

The Attempt at a Solution


I did it by aligning them one under another and tying Vref into one point but I am confused by the fact there is no ground.
