We propose a circuit arrangement that exploits the sense coil of a planar PCB fluxgate to generate the compensation static field in the closed loop configuration. This approach allows to overcome the difficulties related to the optimization of the coupling efficiency between compensation and sense coil. Experimental results are presented to demonstrate the feasibility of the proposed approach.

Abstract
We propose a circuit arrangement that exploits the sense coil of a planar PCB fluxgate to generate the compensation static field in the closed loop configuration. This approach allows to overcome the difficulties related to the optimization of the coupling efficiency between compensation and sense coil. Experimental results are presented to demonstrate the feasibility of the proposed approach.
