Fabrication and characterization of CNT inductors on flexible plastic substrates

Diao L., Shih W-S, Lamb J., Brewer Science, US

A scalable and compact inductor is one of the critical components for passive radio (RF) frequency devices and sensors. CNT thin films have high yield strength and flexibility at high temperature. RF sensors made of [...]

Fully On-Chip High Q Inductors Based on Microtechnologies

Shah K., Khalid N., Singh J., Le H.P., Devlin J., Sauli Z., La Trobe University, AU

The fast growing demand of wireless communications for voice and data has driven recent efforts to dramatically increase the levels of integration in radio frequency (RF) transceivers. Passive components such as inductor play important role [...]

Fabrication of Cu-encapsulated Carbon Nanotube Inductors

Lee B.C., Lee J-O, Lee B.C., Lee J-O, Choi Y.K., Yoon J.-B., Korea Institute of Science and Technology(KIST), KR

In this works, we developed a top-down fabrication method to pattern and form carbon nanotube(CNT) interconnects with Cu encapsulation. Using this method, we fabricated spiral Cu-encapsulated CNT inductors for RF ICs and investigated the inductance [...]

Integrated High Frequency RF Inductors with Nano/micro Patterned Ferromagnetic Cores

Zhuang Y., Vroubel M., Rejaei B., Burghartz J.N., Delft University of Technology, NL

Integration of magnetic material has been long proposed to potentially improve performance and shrink size of on-chip inductive RF/microwave components, e.g. inductors, transformers, and transmission lines, which is crucial for the development of cost-effective RF/BiCMOS [...]

A MEMS Tunable Inductor

Zine-El-Abidine I., Okoniewski M., McRory J.G., University of Calgary and TRLabs, CA

This paper reports a single-wafer micromachined radiofrequency (RF) inductor that can be integrated in a conventional RFIC device. The inductor achieved a quality factor greater than 9 at 5Ghz and a self-resonance frequency well above [...]

Design Optimization of Micromachined High Aspect Ratio 3D On-Chip Solenoid Inductor

Chomnawang N., Lu H., Colinjivadi K., Lee J., University of Texas at Dallas, US

We report the simulation work done by using Sonnet EMÔ on high aspect ratio (1:4 and 1:8) 3D on-chip air-core solenoid inductors. Simulations on 2, 3, and 5-turn inductors with 200 and 400 mm high [...]

An Automatic Macro Program developed for Characterization, Parameter Extraction and Statistic Analysis of Spiral Inductors

Huang G.W., Chiu D.Y., Chen K.M., National Nano Device Laboratories, TW

In the paper, a macro program based on Agilent IC-CAP software is developed for characterization, parameter extraction and statistic analysis of on chip spiral inductors. All procedures can be finished very easily in few buttons [...]
