Hi all, i am trying to simulate the circuit below using multisim but its is proving to be a bit tedious(This picture is from a reliable journal). As can be seen, the omp amp is connected directly to 2 voltages and there is no feedback?? surely there has to be feedback for the circuit to function.
Additionally even if i insert a resistor(between op amp -ve terminal and output) to provide feedback and make the circuit functional, the current through poly_sensor Resistor is not constant anymore.
So basically I am trying to get this circuit to function whilst keeping current through poly_sensor Resistor constant. Any suggestions??
