  • Publication number: 20190198602
    Abstract: Integrated circuits such as multi-channel receivers may require loop inductors resistant to electromagnetic field interference. Such loop inductors may include multiple non-overlapping loops each defining a corresponding dipole, the multiple dipoles summing to zero, with at least one of said loops having unequal areas. The multiple non-overlapping loops may include: a center loop defining a central magnetic dipole; and a plurality of peripheral loops equally spaced around a perimeter of the center loop, each peripheral loop defining a peripheral magnetic dipole oriented opposite the central magnetic dipole, the plurality of peripheral loops substantially canceling a field from the central magnetic dipole. The total number of loops may be odd, with particular embodiments of three, five, and seven loop designs disclosed. Single and multi-turn embodiments are provided.
