Embodiment Construction

[0032] refer to figure 1 , a particular illustrative embodiment of system 100 is shown. System 100 includes electronics 116, inductor 102 (e.g., a planar spiral inductor or a multilayer power inductor), at least one variable magnetic flux density component (VMFDC) (e.g., configurable to selectively Components that adjust the magnetic field) such as the first VMFDC 104 , the controller 108 , and the antenna 114 . The controller 108 may include a processor 110 connected to a memory 112 . Inductor 102 may be used to facilitate impedance matching between antenna 114 and another circuit or component of electronic device 116 , such as controller 108 , when antenna 114 is used to communicate over a particular communication channel. Inductor 102 may be part of a resonant circuit (LC circuit) for a multiband voltage controlled oscillator (VCO) or part of another circuit in a radio frequency (RF) stage of a mobile phone. In a particular embodiment, inductor 102 is included as part of...

Abstract

Inductors are disclosed that can be tuned by variable flux density components. One particular device includes an inductor. The device further includes a variable magnetic flux density component (VMFDC) positioned to affect the magnetic field of the inductor when current is applied to the inductor.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to commonly owned US Nonprovisional Patent Application No. 13 / 887,633, filed May 6, 2013, the contents of which are expressly incorporated by reference herein in their entirety. technical field [0003] The present disclosure generally relates to inductors that can be tuned by variable flux density components. Background technique [0004] Technological advances have produced smaller and more powerful computing devices. For example, a wide variety of portable personal computing devices currently exist, including wireless computing devices that are small, lightweight, and easily carried by users, such as portable wireless telephones, personal digital assistants (PDAs), and paging devices. More specifically, portable wireless telephones, such as cellular telephones and Internet Protocol (IP) telephones, can communicate voice and data packets over wireless networks. In addition, many suc...
