Time and statistical information utilization in high efficiency sub-micron CMOS successive approximation analog to digital converters

Creator:: Guerber, Jon
Abstract:: In an industrial and consumer electronic marketplace that is increasingly demanding greater real-world interactivity in portable and distributed devices, analog to digital converter efficiency and performance is being carefully examined. The successive approximation (SAR) analog to digital converter (ADC) architecture has become popular for its high efficiency at mid-speed and...

A VHDL description of speech recognition front-end

Creator:: Xiao, Xin
Abstract:: This thesis investigates an implementation of speech recognition front-end. It is an application specific integrated circuit (ASIC) solution. A Mel Cepstrum algorithm is implemented for the feature extraction. We present a new mixed split-radix and radix-2 Fast Fourier Transform (FFT) algorithm, which can effectively minimize the number of complex multiplications...

A DSP controlled multi-level inverter providing DC-link voltage balancing, ride-through enhancement and common-mode voltage elimination

Creator:: Dai, Shaoan
Abstract:: With the development of high performance power electronic and semiconductor technologies, Adjustable Speed Drive (ASD) systems are increasingly applied in residential, commercial and industrial applications. Due to the advantages at higher power ratings, the three-level Neutral-Point-Clamped (NPC) Voltage Source Inverter (VSI) is being employed in industrial and traction applications, static...

Design, Fabrication and Characterization of Narrowband Aluminum Plasmonic Grating Filter Array for Spectroscopy in Visible Light Range

Creator:: Shashi, Farzana Hasan
Abstract:: Metal grating based plasmonic filters are widely researched for their unique properties of field enhancement and localization of light beyond diffraction limit. However, the plasmonic grating filters reported in literature mostly have broadband outputs making them unsuitable for spectroscopy. In this project, we have designed, fabricated, and characterized an array...

Quasi-TEM and full wave numerical methods for the characterization on microstrip discontinuities

Creator:: Hill, Achim
Abstract:: Static and dynamic numerical techniques which are suited for the analysis and simulation of various planar microstrip components encountered in hybrid and monolithic microwave integrated circuits are presented. The static analysis makes use of an excess source formulation in conjunction with an efficient mathematical treatment to extract the discontinuity parameter...

Location Assisted Coding (LAC)

Creator:: Nguyen, Thuan
Abstract:: The recent increase in the number of wireless devices has been driven by the growing markets of smart homes and the Internet of Things (IoT). Consequently, current research has focused on efficient utilization of the radio frequency (RF) spectrum to accommodate such an increase in wireless bandwidth. Alternatively, latest free-space...

Resource allocation optimization in large scale distributed systems

Creator:: Duong-Ba, Thuan Hong
Abstract:: We studied the problem of resource allocation in large scale distributed applications such as Online Social Networks (OSN) and Cloud Computing. In such settings, resource allocation schemes need to efficient as well as adaptive to the time-varying environments. The abstract resource allocation problem concerns with how to optimally use resources...

Dual referencing guidelines to minimize power delivery noise coupling

Creator:: Mark, Shannon
Abstract:: Dual referencing has been garnering a lot of attention in the power integrity community, specifically in the voltage mode driver application because it shows a lower overall power delivery noise (PDN) compared to other signal referencing types. Additionally, the increasing push to drive down package and board manufacturing costs is...

A statistical inference framework for finding recurring patterns in large data with applications to energy management

Creator:: You, Zeyu
Abstract:: We consider the problem of finding unknown patterns that are recurring across multiple sets. For example, finding multiple objects that are present in multiple images or a short DNA code that is repeated across multiple DNA sequences. We first consider a simple problem of finding a single unknown pattern in...
