Abstract :
This paper presents an interface circuit suitable for use with differential resistive sensors. The implementation method based on operational conveyors is easily implemented in integrated circuit form. Surpassing the similar circuit using only current conveyors, the proposed configuration affords significant improvement in accuracy. PSPICE simulation and experimental results in good agreement with theoretical analysis are included.
