Suspended Conductor Inductor Layout for Higher Q Factor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic components struggle to improve the Q factor, which is essential for efficient signal processing and filtering in electronic circuits.
Innovation Solution
The electronic component design includes a first and second conductor, a first connection conductor bridged between their ends, and a connecting conductor suspended from the first connection conductor, creating a space that allows for the formation of a magnetic field around the connecting conductor, thereby increasing the apparent volume of the inductor and improving the Q factor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the inductor electrode is arranged with loop surfaces radiating from a central axis, then the structure is compact and suitable for multilayer integration, but the apparent volume of the inductor is limited and the Q factor cannot be improved
Solution Approach 1:
The patent transitions from a planar inductor layout (loop surfaces radiating from central axis) to a three-dimensional configuration by suspending the connecting conductor from the first connection conductor. This vertical arrangement creates additional space for magnetic flux generation, increasing the apparent volume of the inductor without expanding the footprint area, thereby resolving the contradiction between compactness and inductor volume.
Solution Approach 2:
The connecting conductor acts as an intermediary element that bridges the first and second conductors while being suspended from the first connection conductor. This intermediate structure creates the necessary space for magnetic field formation and increases the effective inductor volume, while maintaining the overall structural integrity and compactness of the device.
2Reliability
If the connecting conductor is directly connected to the first connection conductor without suspension, then the structure is simpler, but no space is formed for magnetic field formation and the Q factor remains low
Solution Approach 1:
The connecting conductor is positioned in the vertical dimension by suspending it from the first connection conductor, rather than connecting it directly in the same plane. This dimensional change creates the necessary space for magnetic flux loops, enabling effective magnetic field formation and improving the Q factor while adding minimal structural complexity.
Solution Approach 2:
The suspension configuration creates a localized space around the connecting conductor specifically optimized for magnetic field formation. This local structural adjustment enhances the magnetic flux generation capability in the critical region without requiring complex changes to the entire device structure, thereby improving Q factor with minimal added complexity.
