Zinc tin oxide thin-film transistor circuits

Creator:: Heineck, Daniel Philip
Abstract:: The primary objective of this thesis is to develop a process for fabricating integrated circuits based on thin-film transistors (TFTs) using zinc tin oxide (ZTO) as the channel layer. ZTO, in contrast to indium- or gallium-based amorphous oxide semiconductors (AOS), is perceived to be a more commercially viable AOS choice...

Transmission and Combining for Hybrid Automatic Repeat Request in Multiple-Input Multiple-Output Systems

Creator:: Whang, Younghoon
Abstract:: Hybrid automatic repeat request (HARQ) schemes combine packet retransmission with forward error correction to ensure a reliable communications. In multiple-input multiple output (MIMO) systems, interference cancellation (IC) detection is widely used where the detection and cancellation steps of the simultaneously transmitted data streams occur. In principle, the signal stream estimated...

Time domain modeling of electromagnetic radiation with application to ultrafast electronic and wireless communication

Creator:: Remley, Catherine A.
Abstract:: A versatile computational technique for improved time domain modeling of electromagnetic radiative systems is demonstrated. Two computational methods are combined: the finite-difference time domain (FDTD) method, a full-wave electromagnetic field solver, and the Kirchhoff surface integral formulation, a spatial transformation technique. The combined FDTD/Kirchhoff technique is shown to increase accuracy...

Time domain characterization of interconnect discontinuities

Creator:: Jong, Jyh-Ming
Abstract:: The purpose of this study is to develop experimental techniques to characterize typical interconnect discontinuities, including bends, steps, T junctions, vias and pads, which are the most commonly encountered interconnections in high speed digital integrated circuits, hybrid and monolithic microwave circuits and electronic packages. The time domain reflection response of...

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...

The design of delta-sigma modulators for multi-standard RF receivers

Creator:: Liu, Mingliang
Abstract:: The transition from second-generation (2G) to third-generation (3G) wireless cellular and cordless telephone systems requires multi-standard adaptability in a single RF receiver equipment. An important answer to this request is the use of Delta-Sigma modulators for IF-to-baseband conversion, which will satisfy the dynamic range requirements for digital signal processing, and...

Test fixture characterization for high-frequency silicon substrate parasitic extraction

Creator:: Tabalujan, Andrew R.
Abstract:: At frequencies exceeding 1-2 GHz, the reactive nature of a silicon substrate must be accounted in the substrate network models used in substrate coupling simulation. High-frequency substrate models, containing reactive components, must be validated through high-frequency network analyzer measurements. Prior fabricated test fixtures have been modified to enable high-frequency (up...

Surface-Normal Modulation of Fano Resonances in Metallic Photonic Crystals for Free-Space Optical Interconnects

Creator:: Ren, Fanghui
Abstract:: This dissertation focuses on the development of ultra-compact optical devices for free-space modulation. We propose a surface-normal modulator using metallic photonic crystals for free-space optical interconnects. The active control of light intensity is achieved by engineering the Fano resonances in metallic photonic crystals. Both thermo-optic modulation and electro-optic modulation of...
