Characterization of a digital phase locked loop and a stochastic time to digital converter

Creator:: Geissenhainer, Erik D.
Abstract:: A digital phase locked loop (DPLL) and a statistical time-to-digital converter (STDC) were previously fabricated in a 0.35Âµm, 3.3V SOI CMOS process. This work summarizes these designs and characterizes the measured performance. Simulations supplement the measurements where applicable. The DPLL was found to reach a locked state under a limited...

Analysis and synthesis of neural networks

Creator:: Skelton, Jeanette K.
Abstract:: The brain has long attracted the interest of researchers. Some tasks, such as pattern recognition and optimization, have proven to be exceptionally difficult for conventional computing systems to perform, but are executed by the brain almost effortlessly. Due to the large number of neurons and interconnections, it has proven impossible...

Analysis and modeling of substrate noise coupling for NMOS transistors in heavily doped substrates

Creator:: Hsu, Shu-ching
Abstract:: This thesis examines substrate noise coupling for NMOS transistors in heavily doped substrates. The study begins with the analysis of an NMOS transistor switching noise in a digital inverter at the device level. A resistive substrate network for the NMOS transistor is proposed and verified. Coupling between N+- P+ contacts...

Design of low power 2.4GHz CMOS LC balanced oscillators with low phase noise and large tuning range

Creator:: Seshan, Nilakantan
Abstract:: The design of two 2.4GHz CMOS LC balanced oscillators in the 0.25μm National BiCMOS process for Bluetooth specifications is presented. These oscillators achieve low phase noise with low power consumption. At a frequency offset of 500KHz from the 2.11GHz carrier, the measured phase noise is -101.9dBc/Hz for the NMOS oscillator...

Studies in food science for industrial applications : Chemical and sensory analysis of fermented cucumbers; insoluble chitosanpolyacrylic acid complexes

Creator:: Chavasit, Visith
Abstract:: Pediococcus cerevisiae, Lactobacillus casei, Lactobacillus plantarum, Leuconostoc mesenteroides, Lactococcus diacetylactis Bifidobacterium bifidum, Leuconostoc oenos, and mixed cultures of Propionibacterium shermanii and P. cerevisiae were used to ferment cucumber juice brine (CJB) at 22-26°C for 1.5 months. Sugar utilization ranged from 14.6 to 86.1%. pH of the fermented CJB ranged from...

A comprehensive integration of first year engineering education

Creator:: Shuman, Matthew W.
Abstract:: Retention of engineering students is a problem for many universities, especially during the first year. The problem of introducing students to engineering while increasing retention rates has recently been addressed by many different universities. Implementing novel lab structures, adjusting the lecture to incorporate more effective teaching techniques, and using orientation...

Fabrication of Biological Pigment Nanowires by Inkjet Printing

Creator:: Cao, Yu
Abstract:: Digital inkjet printing is developing quickly today because inkjet printing processes consume less energy and water and produce less waste discharge than traditional dyeing and other printing technologies. Inkjet printing provides more versatility and flexibility in terms of printing patterns and colors. Natural pigments are gaining more attention today as...

Growth and characterization of zinc ferrite thin films for high frequency applications

Creator:: Hu, Jiqing
Abstract:: Ferrites have been used for various high frequency applications as bulk materials. These applications, however, are limited to large dimension devices. In this thesis, thin film ferrites were deposited from a low temperature solution-based deposition process that is suitable for micro-scale high frequency applications. The low temperature nature of this...
