Title:
ENHANCED INDUCTORS SUITABLE FOR INTEGRATED MULTI-CHANNEL RECEIVERS
Document Type and Number:
WIPO Patent Application WO/2018/018441
Kind Code:
A1
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, such as three, five, or seven. The inductors could be single-turn or multi-turn.
