Abstract
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 where M=N−1, and S(i) is the measured signal read at magnetic field based current sensor i.
