Design, Fabrication, and Dynamic Modeling of a Printed Circuit Based MEMS Accelerometer
(2008-09-09)
A MEMS capacitive-type accelerometer fabricated using printed circuit processing techniques is presented. A Kapton polymide film is used as the structural layer for fabricating the MEMS accelerometer. The accelerometer ...
Design of a Geotextile Roadbed Antenna to Create a Wireless Highway Network
(2008-09-09)
Incorporation of antennas into geotextile fabric to create a roadbed reinforcement with electronic transmission capabilities may find use in expanding communications infrastructures. The design of a model transmission ...
A Tunable Coplanar Patch Antenna, a Polymer MEMS Based Tunable Bandpass Filter, and a Chip-In-Polymer Packaging Technology
(2008-09-09)
This thesis presents a tunable coplanar patch antenna, a Polymer MEMS-based tunable bandpass filter, and a chip-in-polymer packaging technology. First, a Coplanar Waveguide (CPW) based patch antenna is integrated with a ...
Analysis of DC Power Systems Containing Induction Motor-Drive Loads
(2008-09-09)
The development of an analytical method used for conducting a power flow analysis on a DC power system containing multiple motor-drive loads is presented. The method is fast, simplistic, easy to implement, and produces ...
Integration of Thin Flip Chip in Liquid Crystal Polymer Based Flex
(2008-09-09)
Thin embedded active assemblies have been developed that combine a lower profile and high functional density (per volume) with a flexible appearance, meeting the demands for the miniaturization of electronic products. The ...
Nonlinear Systems Control Using a Subset Stabilization Approach
(2008-09-09)
Numerous problems in nonlinear control systems are difficult or impossible to solve with commonly proposed methods of design. For such systems, we propose a two-loop control strategy that we call the subset stabilization ...
Design and Implementation of Digital Controllers for Buck and Boost Converters Using Linear and Nonlinear Control Methods
(2009-02-23)
Issues in the design and implementation of digital controllers for a buck converter and a boost converter using linear and nonlinear control methods were investigated in this dissertation. The small signal models of the ...
Radio Frequency Integrated Circuits for Wireless and Wireline Communications
(2009-02-23)
This dissertation presents my studies in design of high frequency circuits for wireless and wireline communication systems.
As a part of this effort a seven tap transversal filter has been designed using broadband amplifiers. ...
Frequency Syntheses with Delta-Ssigma Modulations and their Applications for Mixed Signal Testing
(2009-02-23)
This dissertation presents design and application of two popular frequency synthesizers, namely, the direct digital frequency synthesis (DDS) and phase lock loop (PLL) synthesis.
DDS is a digital technique for frequency ...
Lead-Free Assembly and Reliability of Chip Scale Packages and 01005 Components
(2009-02-23)
Chip Scale Packages (CSPs) are widely used in portable and hand-held electronic devices due to their small size and availability. Consumers expect portable products to survive being dropped repeatedly, and drop testing is ...
