Title:
APPARATUS AND METHODS FOR VECTOR INDUCTORS
Document Type and Number:
WIPO Patent Application WO/2014/193845
Kind Code:
A3
Abstract:
Apparatus and methods for vector inductors are provided herein. In certain configurations, an apparatus includes a vector inductor comprising a plurality of conductors arranged in a stack and separated from one another by dielectric. The conductors are tightly coupled to one another to provide a relatively high amount of mutual inductance. For example, adjacent conductors in the stack can be mutually coupled with a coupling coefficient k that is at least 0.5, or more particularly, 0.9 or greater. In certain implementations, the conductors are electrically connected in parallel with one another to provide the vector inductor with low resistance. However, tight coupling between the conductors in the stack can result in vector inductor having an overall inductance that is similar to that of a self- inductance of an individual conductor in the stack. The Q-factor of the vector inductor can be increased by the inclusion of additional conductors in the stack.
