Abstract
A current sensing cell, using PCB trace-loops, with the loops either contained in a single layer—horizontal loops, or in two separate layers—vertical loops interconnected by vias into a single two-pole inductive component. The horizontal loop-sensor cell will be used sideways, next to a planar conductor carrying a current parallel to the sensor traces, so as to collect the magnetic field lines on the side of the planar conductor, where they come closer together. The vertical loop sensor cell will be used on top or bottom of a planar conductor carrying current parallel to the cell, so as to collect the magnetic field lines going across the conductor, or between two parallel conductors, carrying parallel current of opposite sense, so as to collect the magnetic field lines that run in between the two conductors, summing up the two fields.
