Abstract
Systems, methods, and devices are provided for producing and using a low-value inductor which is stable at high frequencies, the inductor including a plurality of radial spokes extending between two concentric rings. The inductance of the inductor is controlled by the number and dimensions of the plurality of spokes, as well as the materials of the inductor. In some cases, the inductor is used as a low value inductance standard for directly measuring a low value electrical inductance.
Claims20
An inductor comprising:
- an inner ring;
- an outer concentric ring forming an outer perimeter;
- and
- a plurality of spokes extending radially from the inner ring to the outer ring, each of the plurality of spokes secured to the inner ring at a first end and secured to the outer ring at a second end,
- wherein the plurality of spokes provides an electrical resistance and a stable electrical inductance based at least in part on a number of spokes in the plurality of spokes, and
- wherein the inductor is configured to provide a nanohenry inductance value at a frequency equal to or greater than about 100 kilohertz.
A low value inductor system comprising:
- a non-conductive base portion;
- and
- a conductive inductor portion disposed on a surface of the base portion comprising:
- an inner ring;
- an outer concentric ring;
- and
- a plurality of equidistantly spaced spokes extending radially from the inner ring to the outer ring, each of the plurality of spokes secured to the inner ring at a first end and secured to the outer ring at a second end, the plurality of spokes providing an electrical resistance and a stable electrical inductance based at least in part on a number of spokes in the plurality of spokes.
A method for providing a low value inductor comprising:
- determining one or more materials for the inductor based at least in part on an electrical conductivity;
- determining a number of spokes and one or more dimensions of a plurality of spokes to achieve a desired inductance for the inductor based at least in part on the one or more materials;
- depositing at least one layer of material onto a substrate surface to form the inductor, wherein the inductor comprises:
- an inner ring;
- a concentric outer ring;
- and
- a plurality of spokes extending radially from the inner ring to the outer ring, each of the plurality of spokes secured to the inner ring at a first end and secured to the outer ring at a second end, the plurality of spokes providing an electrical resistance and a stable electrical inductance based at least in part on the number of spokes in the plurality of spokes.
