Abstract
A planar microstrip inductor formed from a spiral shaped conductive path of material on a dielectric uses a bifilar spiral by which both the connection nodes of the inductor can be brought out to the edge of the substrate. The bifilar winding by which both connection nodes are available from the exterior of the spiral shape includes the use of a jumper wire to connect the inner node of the inductor to a circuit.
