Patent number: 8841983Abstract: 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.Type: GrantFiled: August 27, 2009Date of Patent: September 23, 2014Assignee: Cambridge Silicon Radio LimitedInventors: Timothy John Newton, Nicolas Sornin, Johan Lucas Gertenbach
