This Small Business Technology Transfer Phase I research project will develop die-area-efficient tunable magnetically enhanced inductors for use in Radio Frequency (RF) Integrated Circuits (IC). This project is to explore magnetic materials and inductor geometries with the goal of achieving area efficient, tunable, high Q inductors that operate at frequencies up to 6 GigaHertz (GHz) or more. In particular, the project will explore the use of magnetic alloys with ferromagnetic resonance that is significantly higher than that of permalloy in order to allow high-Q operation at frequencies up to 6GHz. The project will also explore multiple geometries for the magnetic cores, the current carrying conductors, and the inductance control conductors. As demand for RF communications bandwidth continues to increase, the need for frequency agile radios is growing. As feature sizes shrink, RF front end ICs in cell phones require up to 80% of their die area for inductors and area under inductors must be empty, increasing cost of future multi-band radios. This project could lead to the creation of frequency agile radios and could greatly reduce the cost of radios (allowing many radios to be integrated together at the cost of a single radio today). RF front end circuits that employ magnetically enhanced inductors have the potential to achieve much smaller die area, less cross talk compared to inductors used in today's cell phone RF front end ICs.

这个小型企业技术转移阶段研究项目将开发可在射频（RF）集成电路（IC）中使用的磁性可调式磁性电感器。该项目旨在探索磁性材料和电感器几何形状，目的是实现面积有效，可调，高Q电感器，该Q电感器以高达6吉赫兹（GHz）或更多的频率运行。特别是，该项目将探索具有铁磁共振的磁合金的使用，该合金的使用显着高于Permalloy的磁合金，以便在高达6GHz的频率下允许高Q运行。该项目还将探索磁芯，电流载体导体和电感控制导体的多种几何形状。随着RF通信带宽的需求不断增加，对频率敏捷无线电的需求正在增长。随着特征尺寸的收缩，手机中的RF前端IC需要其在电感器和电感器下的电感区域的80％，必须是空的，这会增加未来的多波段收音机的成本。该项目可能会导致频率敏捷无线电的创建，并可以大大降低无线电成本（使许多无线电以当今的单个无线电为代价将许多收音机集成在一起）。与当今手机RF前端IC中使用的电感器相比，使用磁性增强电感器的RF前端电路有可能达到更小的模具区域，交叉谈话较小。
