Abstract
An inductor structure includes a first inductor and a second inductor. The second inductor includes a loop that surrounds the first inductor. The first inductor includes a first loop and a second loop, and a crossover section coupling the first loop to the second loop so as to cause current flowing through the first inductor 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 first and second inductors are arranged in an equilibrated configuration about a first axis that bisects the inductor structure such that the first loop is on one side of the first axis and the second loop is on a second side of the first axis, such that the magnetic interaction between the inductors due to current flow in the inductors is cancelled out.
