Switch-capacitor Power Amplifier with Enhanced Power Back-off Efficiency and Linearity

Creator:: Qiao, Bo
Abstract:: Nowadays, wireless communication systems use high-order quadrature amplitude modulation (QAM) together with orthogonal frequency-division multiplexing (OFDM) to increase the link capacity and robustness. These signals always have large peak-to-average power ratio (PAPR) and require power amplifiers (PAs) achieve both high efficiency and linearity simultaneously. For the efficiency, the complementary metal...

gm/ID Design Techniques for Low-power High-performance CMOS Analog Integrated Circuits

Creator:: Aueamnuay, Chaiyanut
Abstract:: The gm/ID-based design of analog integrated circuits introduced in 1996 employs an empirical transistor sizing methodology using SPICE-generated lookup tables that enables good agreement between simulations and specifications. This thesis introduces a new SPICE lookup table that extends the gm/ID approach to the Miller pole-splitting frequency compensation of the classical...

Investigation of metal-insulator-metal (MIM) and nanolaminate barrier MIIM tunnel devices fabricated via atomic layer deposition

Creator:: Alimardani, Nasir
Abstract:: Metal-insulator-metal (MIM) tunnel devices have been proposed for high speed applications such as hot electron transistors, IR detectors, optical rectennas for IR energy harvesting, and backplanes for LCDs. The majority of these applications require highly asymmetric and non-linear current versus voltage (I-V) behavior at low applied voltages and ultra-high frequencies....

Using provenance to aid document re-finding

Creator:: Lonsdale, Heather
Abstract:: In the field of Human-Computer Interaction, provenance refers to the complete history and genealogy of a document. Provenance can be useful in identifying related resources, such as different versions of the same document or resources used in the creation of a new document. Though methods of provenance collection and applications...

Leyline : a provenance-based desktop search system using graphical sketchpad user interface

Creator:: Ghorashi, Seyed Soroush
Abstract:: While there are powerful keyword search systems that index all kinds of resources including emails and web pages, people have trouble recalling semantic facts such as the name, location, edit dates and keywords that uniquely identifies resources in their personal repositories. Reusing information exasperates this problem. A rarely used approach...

Investigation of the impact of insulator material on the performance of dissimilar electrode metal-insulator-metal diodes

Creator:: Alimardani, Nasir, King, Sean W., French, Benjamin L., Tan, Cheng, Lampert, Benjamin P., and Conley, John F., Jr.
Abstract:: The performance of thin film metal-insulator-metal (MIM) diodes is investigated for a variety of large and small electron affinity insulators using ultrasmooth amorphous metal as the bottom electrode. Nb2O5, Ta2 O5, ZrO2, HfO2, Al2 O3, and SiO2 amorphous insulators are deposited via atomic layer deposition (ALD). Reflection electron energy loss...

Comprehensive depletion-mode modeling of oxide thin-film transistors

Creator:: Zhou, Fan
Abstract:: The primary focus of this thesis is modifying the comprehensive depletion-mode model and extending its applicability to p-channel thin-film transistor (TFT) behavior and subthreshold (subpinchoff) operation. The comprehensive depletion-mode model accurately describes depletion-mode TFT behavior and establishes a set of equations, different from those obtained from square-law theory, which can...

Plasmonic color filter array, high performance analog to digital converter architectures and novel circuit techniques

Creator:: Shakya, Jyotindra R.
Abstract:: Part I: Plasmonic color filters can be manufactured at lower cost since they can be fabricated in single lithographic process step as compared to Fabry-Perot based filters. In addition, they have narrow passband making resolving sharp features in sample spectrum possible. Due to these benefits, in this thesis, Plasmonic color...

Activity recognition in desktop environments

Creator:: Shen, Jianqiang
Abstract:: Knowledge workers are struggling in the information flood. There is a growing interest in intelligent desktop environments that help knowledge workers organize their daily life. Intelligent desktop environments allow the desktop user to define a set of “activities” that characterize the user’s desktop work. These environments then attempt to identify...
