Description

In this SPICE simulation the circuit measures an unknown resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown component, detecting the zero voltage with a multimeter when the balance is reached, with reference to this circuit when R1/R2 = R3/Rpot.The potential small voltage differences are amplified by a low power instrumentation amplifier AD620.
