Abstract
An inductor structure comprising: a first loop and a second loop; a first feed line connected to a first end of the first loop and a second feed line connected to a first end of the second loop, each of the first and second feed lines extending through an area circumscribed by one of the first and second loops; and a crossover section adjacent to the first end of the first loop and the first end of the second loop, the crossover section coupling the first loop to the second loop so as to cause current flowing from the first feed line to the second feed line to circulate around the first loop in a first rotational direction and around the second loop in a second rotational direction opposite to the first rotational direction.

An inductor structure for incorporation on a chip into an integrated circuit comprising:
- a first loop and a second loop;
- a first feed line connected to a first end of the first loop and a second feed line connected to a first end of the second loop, wherein the first feed line extends through an area circumscribed by one of the first and second loops and the second feed line extends through an area circumscribed by the same one of the first and second loops;
- and
- a crossover section adjacent to the first end of the first loop and the first end of the second loop, the crossover section coupling the first loop to the second loop so as to cause current flowing from the first feed line to the second feed line to circulate around the first loop in a first rotational direction and around the second loop in a second rotational direction opposite to the first rotational direction.
An inductor structure comprising:
- a first loop and a second loop;
- a first feed line connected to a first end of the first loop at the centre of the inductor structure and a second feed line connected to a first end of the second loop at the centre of the inductor structure, each of the first and second feed lines extending out of the plane of the inductor structure;
- and
- a crossover section adjacent to the first end of the first loop and the first end of the second loop, the crossover section coupling the first loop to the second loop so as to cause current flowing from the first feed line to the second feed line to circulate around the first loop in a first rotational direction and around the second loop in a second rotational direction opposite to the first rotational direction, wherein the facing edges of the first and second loops are parallel, the facing edges being those adjacent to an axis which divides the inductor structure such that the first loop is on one side of the axis and the second loop is on the other side of the axis.
