A system for measuring current includes a conductive trace comprising N substantially parallel straight sections having a substantially constant cross-section, N≥4. Adjacent substantially straight sections are spaced apart by a given distance and each pair of adjacent straight sections is connected by a respective loop of the current trace such that current in odd-numbered straight sections flows in a first direction and current in even-numbered straight sections flows in an opposite direction. The N magnetic field based current sensors are each positioned on a respective straight section of the conductive trace. The current is calculated based on ( S ⁡ ( 1 ) - ( N - 1 1 ) ⁢ S ⁡ ( 2 ) + ( N - 1 2 ) ⁢ S ⁡ ( 3 ) - … - ( N - 1 N - 3 ) ⁢ S ⁡ ( N - 2 ) + ( N - 1 N - 2 ) ⁢ S ⁡ ( N - 1 ) - S ⁡ ( N ) ) 2 ( N - 1 ) ; ( M k ) = M ! ( M - k ) ! ⁢ k ! ; where M=N−1, and S(i) is the measured signal read at magnetic field based current sensor i.
