Low power high resolution data converter in digital CMOS technology

Creator:: Zheng, Zhiliang
Abstract:: The advance of digital IC technology has been very fast, as shown by rapid development of DSP, digital communication and digital VLSI. Within electronic signal processing, analog-to-digital conversion is a key function, which converts the analog signal into digital form for further processing. Recently, low-voltage and low-power have become also...

Multi-bit delta-sigma switched-capacitor DACs employing element-mismatch-shaping

Creator:: Lin, Haiqing
Abstract:: Delta-sigma modulators are currently a very popular technique for making high-resolution analog-to-digital and digital-to-analog converters (ADCs and DACs). Most delta-sigma modulators in production today employ single-bit quantization because a 1-bit DAC is inherently linear, whereas a multi-bit DAC is not. Were it not for this drawback, the use of multi-bit...

High-accuracy circuits for on-chip capacitor ratio testing and sensor readout

Creator:: Wang, Bo, 1970-
Abstract:: The precise measurement of a capacitance difference or ratio in a digital form is very important for capacitive sensors, for CMOS process characterization as well as for the realization of precise switched-capacitor data converters, amplifiers and other circuits utilizing ratioed capacitors. This thesis introduces design techniques for on-chip capacitor ratio...

Design of a 1.8-V 14-bit [delta] - [sigma] A/D converter with 8X oversampling and 4 MHz Nyquist output rate

Creator:: Jiang, Ruoxin
Abstract:: In this dissertation, a new Δ∑ A/D converter is presented that is ideally suited for communication applications. It is based on a single-loop single-stage structure, which can realize a high maximum out-of-band quantization noise gain while maintaining stable operation and thus achieve 14-bit resolution at 8 times oversampling. A fifth-order...

Case Study: Pisgah Nantahala National Forest Plan Revision and American Ginseng Management

Creator:: Swartz, Shawn C.
Abstract:: The Pisgah and Nantahala National Forests (PNNF) are located in the Southern Appalachian Mountains. A center of biological diversity, they are also within a few hours’ drive of much of the population of the United States. Therefore, there are many desires and objectives the public has for how these national...

Effects of ultraviolet-B radiation on marine phytoplankton

Creator:: Behrenfeld, Michael Joseph
Abstract:: Global increases in ultraviolet-B radiation (UVBR:290- 320 nm) resulting from decreases in stratospheric ozone concentration have the potential to alter marine primary production and affect global climate and marine trophic dynamics. Effects of UVBR on phytoplankton carbon fixation were determined from open ocean exposure studies conducted off the coast of...

Full-Scale Experimental Investigation of the Seismic Capacity of Reinforced Concrete Column-Footing Specimens Retrofitted with Titanium Alloy Bars Considering Effects of Soil-Structure Interaction on Vintage and Retrofitted Column-Footing Specimens

Creator:: McGinn, Logan
Abstract:: Reinforced concrete (RC) column-footing substructures are widely used to support bridges along critical transportation corridors in Oregon. Those built prior to 1971 were typically designed to resist only gravity loads. Therefore, they are vulnerable to damage or collapse during strong ground shaking. To prevent collapse, seismic retrofits have been developed...

Classification strategies for unbalanced binary maps : finding Ponderosa pine in the Willamette Valley

Creator:: Riddell, Audrey P.
Abstract:: Forest species classifications are becoming increasingly automated as advances are made in machine learning. The algorithms used to identify tree species range from simple decision trees to intricate neural networks, and often excel in accurately delineating tree species. However, complex algorithms can have high input costs, including the cost of...

Improved stability in ACTFEL devices

Creator:: Khormaei, Iranpour
Abstract:: The stability of ZnS:Mn AC thin film Electroluminescence (ACEFEL) devices as demonstrated by the brightness-voltage (BV) characteristics is discussed. Two procedures for improvement of the stability are demonstrated. The first method is the addition of a CaS buffer layer to one or both interfaces of the ZnS active phosphor layer....
