Plasma enhanced growth of carbon nanotubes

Creator:: Ford, Neil I.
Abstract:: Carbon nanotubes (CNTs) are grown using plasma enhanced chemical vapor deposition (PECVD). A modified radio frequency (RF) parallel-plate plasma etching system serves as the growth reactor. The effects of process parameters, including temperature, pressure, and C2H2:NH3 ratio, are studied. CNTs are grown on glass substrates with Al underlayers and Ni...

Feasibility study for the use of a fuel cell to process landfill gas at Coffin Butte Landfill : hydrogen sulfide (H2S) detection and removal

Creator:: Tuinstra, Hannah May
Abstract:: Pacific Northwest Generating Cooperative (PNGC) operates the Landfill Gas to Energy Facility at Coffin Butte Landfill in Corvallis, OR. At this facility, three internal combustion engines use the landfill gas (predominantly methane and carbon dioxide) as fuel to turn generators that produce enough electricity to power 1,800 average sized homes....

Substrate noise coupling in ring oscillator-based phase locked loops

Creator:: Shreeve, Robert
Abstract:: In this thesis, the performance degradation of a phase-locked loop due to substrate noise is examined. A new analytical equivalent circuit model for substrate noise coupling is derived for a heavily doped silicon substrate. The model has been validated with measured data from a 0.35 μm CMOS process. Since the...

Simulation and modeling of substrate noise generation from synchronous and asynchronous digital logic circuits

Creator:: Hanken, Christopher
Abstract:: Efficient methods for simulating the substrate noise generated by complex synchronous and asynchronous digital logic circuits are presented. By simulating digital logic at the gate level, and precharacterizing the gates, the substrate noise generation can be predicted and used in a transistor level simulation of the sensitive analog blocks. This...

Noise optimization for low-voltage CMOS audio preamplifier systems

Creator:: Brown, Matthew Eugene
Abstract:: There is a large and growing market for portable consumer audio products with very small size. As the size of these products is reduced, the area occupied by batteries becomes significant and hence limits the number of batteries to one. In order to build such small products, high levels of...

A test fixture and deembedding procedure for high-frequency substrate characterization

Creator:: Webb, Kyle M.
Abstract:: At frequencies exceeding 1-2 GHz, the substrate network models used in substrate coupling simulation must account for the reactive nature of the substrate. Unlike at low frequencies, where the purely resistive substrate models can be validated through DC resistance measurements, these high-frequency models, comprising reactive components, must be validated through...

Analysis and Design of Low Voltage LC Oscillators and their Application to Wireless Sensor Networks

Creator:: Guha Roy, Ankur
Abstract:: This dissertation focuses on the analysis, design, and application of inductor-capacitor (LC) oscillators for wireless sensor networks (WSNs). First an analysis and design optimization approach for enhanced swing, low power CMOS LC oscillators is presented. A phasor based analysis is used for determining the amplitude and phase noise of these...

Simulations of geckos dry adhesion system

Creator:: Hu, Congcong
Abstract:: Simulation models were developed to explore the reversible nature of gecko dry adhesion system. The central idea of this model is that even with a small moment imparted on the contact tip, the seta can be easily ad-adhered. It is shown that this contact condition is very sensitive, but can...

Adaptive broadband wireless interference mitigation architecture applying higher order statistics algorithm for computer platform

Creator:: Wang, Qiwei
Abstract:: The broadband wireless interference in a computer platform is resulted by multiple electro-magnetic emission sources. This non-Gaussian interference is proved to be double-sided K-distributed in previous research. With the limitation of transmission power and dimension of the device, interference mitigation is an efficient way to improve received signal bit error...

Optimal communications system design for array-based electric generation

Creator:: Orozco, Ricardo
Abstract:: The world's demand for energy is an ongoing challenge, which has yet to be overcome. The efforts to find clean energy alternatives to fossil fuels have been hampered by the lack of investment in technology and research. Among these clean energy alternatives are ocean waves and wind. Wind power is...
