Novel, high performance on-chip tunable components and crosstalk suppression schemes using magnetic thin films

无线通信领域的最新进展需要高性能的射频电路才能有效地在片上实现。该项目的重点是开发一种新型的柔性和可调谐射频集成电路，通过新的设备设计和新的材料使用来实现。为了实现这一目标，这项工作将探索磁性材料可用于无线设备和系统可调的新方法。具体而言，我们建议在无线设备和系统设计方面取得三个主要进展：1)将结合新颖的结构几何形状和铁氧体薄膜开发固定和可调谐的高性能集成无源元件，如集成电感器。2)提出铁氧体薄膜片上可调谐传输线的新方案。3)首次提出了利用高损耗、高磁导率铁磁薄膜抑制噪声和串扰的方案。在该项目的第四个也是最后一个要素中，我们建议开发各种片上测试结构，以证明新配置在紧凑性，改进性能，可调性和串扰抑制方面的优势。虽然我们将尽一切努力完成最初提出的研究范围，但由于修订后的可用资源，我们修改了范围，以解决以下主要研究目标：1。研究高电感、高质量因数铁氧体电感的新拓扑结构，使其紧凑并与片上技术兼容。2. 开发新的锁存方案来控制铁氧体材料的磁性能，适用于片上可调谐电感器和具有可控特性的传输线。开发高损耗铁磁薄膜的创新应用，以抑制片内噪声/串扰。将研究各种可能的布局方案。开发合适的铁氧体电镀技术以实现有效的片上实现5。开发微机械加工技术的新用途，以制造拟议的结构。6. 开发一个磁性可调谐带通滤波器来演示其可调谐性。开发合适的片上互连结构来演示串扰抑制。制造用于片上实现的磁性可调谐器件和组件的能力将对无线行业产生革命性的影响。这项工作是对一系列加工技术、材料和设备设计挑战的第一次认真审视，这些挑战必须得到解决，才能使这一愿景成为现实。ppi强烈鼓励少数民族、妇女和代表性不足的群体成员参与他们的研究项目。

Recent advances in the area of wireless communications demand high-performance radio frequency circuits for effective on-chip implementation. This project focuses on the development of a new and novel class of flexible and tunable radio frequency integrated circuits enabled by new device designs and novel use of materials. To accomplish this goal, this work will explore novel ways in which magnetic materials may be used to make wireless devices and systems tunable. Specifically, we propose to pursue three major advances in wireless device and system design: 1) Fixed and tunable high performance integrated passive elements such as integrated inductors will be developed combining novel structure geometries and ferrite thin films. 2) New schemes for on-chip tunable transmission lines using ferrite thin films will be proposed. 3) For the first time, noise and crosstalk suppression schemes using high-loss, high permeability ferromagnetic thin films will be proposed. In a fourth and final element of the project, we propose to develop a variety of on-chip test structures to demonstrate the advantage of the new configurations in terms of compactness, improved performance, tunability and crosstalk suppression. While we will make every attempt to fulfill the scope of the originally proposed research, due to the revised available resources, we have modified the scope to address the following key research goals: 1. Investigate new topologies for high inductance, high quality factor ferrite inductors that are compact and compatible with on-chip technologies. 2. Develop novel latching schemes for controlling the magnetic properties of the ferrite material that are suitable for on-chip tunable inductors and transmission lines with controllable characteristics.3. Develop innovative use of high-loss ferromagnetic thin films to suppress on-chip noise/ crosstalk. Various schemes for possible layout will be studied.4. Develop suitable ferrite plating technology for effective on-chip implementation5. Develop novel use of micromachining techniques for the fabrication of proposed structures. 6. Develop a magnetically tunable bandpass filter to demonstrate the tunability.Develop suitable on-chip interconnect structures to demonstrate crosstalk suppression. The ability to fabricate magnetically tunable devices and components for on-chip implementation would have a revolutionary effect on the wireless industry. This work is a first serious look at a number of processing techniques, materials, and device design challenges that must be solved to make this vision a reality. The PIs strongly encourage minorities, women and members of under-represented groups to participate in their research program.
