An integrated circuit chip including a first inductor; a second inductor having n1 turns and located a distance r1 from the first inductor; and a third inductor having n2 turns and located a distance r2 from the first inductor; wherein the second and third inductors are coupled so as to cause current to circulate around the second inductor in a first rotational direction and around the third inductor in a second rotational direction opposite to the first rotational direction; and wherein n1, n2, r1 and r2 are such that current induced in the first inductor due to magnetic coupling from the second inductor is negated by current induced in the first inductor due to magnetic coupling from the third inductor.
