Experimental Characterization of the Temperature Dependence of the Piezoresistive Coefficients of Silicon
(2008-09-09)
In this work, the dependence of the silicon piezoresistive coefficients p11, p12, and p44 on temperature is investigated. Experimental calibration results for the piezoresistive coefficients of silicon as a function of ...
Soft Error Rate Determination For Nanometer CMOS VLSI Circuits
(2009-02-23)
Nanometer CMOS VLSI circuits are highly sensitive to soft errors due to envi-
ronmental causes such as cosmic radiation and high-energy particles. These errors are
random and not related to permanent hardware faults. ...
Frequency Synthesizer Designs and Their Applications
(2009-02-23)
This thesis discusses design and applications of two main frequency synthesizers: direct digital frequency synthesis (DDS) and phase lock loop (PLL) synthesis.
DDS is a quickly developed digital technique for frequency ...
Built-In Self-Test for Input/Output Tiles in Field Programmable Gate Arrays
(2008-09-09)
Very large scale integration (VLSI) circuits use input/output (I/O) cells to both send and receive signals from external resources. Field Programmable Gate Arrays (FPGAs) and System-on-Chips (SoCs) with FPGA cores offer ...
Node Placement, Routing and Localization Algorithms for Heterogeneous Wireless Sensor Networks
(2008-09-09)
Wireless sensor network is a very promising technology for many
military and civilian applications. The network usually consists
large number of nodes and many existing network techonlogies can
not be used directly in ...
A Study of Electromagnetic Induction Systems for the Detection of Unexploded Ordnance
(2008-09-09)
This thesis presents a study of a time domain electromagnetic induction (EMI) system used for detection and discrimination of unexploded ordnance. In general, EMI system components include transmitter and receiver coils, ...
Finite Element Analysis of the Mesosphere's Electromagnetic Response to Large Scale Lightning Associated with Sprites and other Transient Luminous Events
(2008-09-09)
In this research, a numerical investigation of high altitude sprites and other mesospheric Transient Luminous Events induced by lightning is presented. A Finite Element Model is created using equations based on a modified ...
Gaseous Discharges and Their Applications as High Power Plasma Switches
(2008-09-09)
Today’s pulsed power technology requires compact systems for both military and civilian applications, leading to increased demand for research in compact system components. High power switches are one of the fundamental ...
A Linear CMOS Tunable Active Resistor
(2008-09-09)
The demand for fast, inexpensive, and accurate sensors is increasing at a staggering
rate. Deciding whether to use analog of digital signal processing for these sensors has become
a challenge. Even though digital systems ...
Wide Range Tunable Transconductance Filters
(2008-09-09)
Generation of filters using operational transconductance amplifiers and capacitors (OTA-C) has become more and more popular over recent years. This is due to the need for high quality analog filters that can be implemented ...
