Abstract
The present description provides an inductor arranged in a stack of insulating and conductive levels. An exemplary inductor includes: in a first area of a stack, at least first and second turns respectively arranged in two distinct conductive levels of the stack; and in a second area of the stack, at least third and fourth turns respectively arranged in two distinct conductive levels of the stack, in which the first, second, third, and fourth turns are series-connected between first and second ends of the inductor, so that a current applied between the first and second ends of the inductor flows in a first rotation direction in the first and second turns and in a second rotation direction opposite to the first direction in the third and fourth turns.
Claims11
An inductor arranged in a stack of insulating and conductive levels, comprising:
- in a first area of the stack, a first turn and a second turn respectively arranged in a first conductive level of the stack and in a second conductive level of the stack, the first conductive level and the second conductive level being distinct;
- in a second area of the stack, at least a third turn and a fourth turn respectively arranged in the second conductive level and in the first conductive level;
- and
- wherein the first turn, second turn, third turn, and fourth turn are series-connected between a first end and a second end of the inductor, so that a current applied between the first end and second end of the inductor flows in a first rotation direction in the first turn and second turn and in a second rotation direction opposite to the first direction in the third turn and fourth turn, wherein the second turn and the third turn are adjacent and define together an eight-shaped conductive track,
- wherein the first turn and the second turn are overlapped, and
- wherein the third turn and the fourth turn are overlapped.
