An On-Chip Transformer-Based Digital Isolator System, Cory Lynn Fandrich
An On-Chip Transformer-Based Digital Isolator System, Cory Lynn Fandrich
Masters Theses
An on-chip transformer-based digital isolator has been designed, fabricated, and tested. This isolation technique is designed to function between a low voltage microcontroller and a potentially high-voltage power control system. The isolator’s isolation capability is determined by two factors, the RMS blocking voltage strength and common-mode transient immunity. The integrated circuit solution is designed in a high-temperature capable SOI process.
The on-chip transformer size is minimized by utilizing high frequency voltage pulses. A small transformer and overall small chip footprint of the design are favorable for integration into a larger system. The isolator is a two chip solution, an isolated …
A Sige Bicmos Lvds Driver For Space-Borne Applications, Matthew Ian Laurence
A Sige Bicmos Lvds Driver For Space-Borne Applications, Matthew Ian Laurence
Masters Theses
When designing an integrated circuit for use during an interstellar mission, certain precautions must be made. The electronics on any off-earth mission will be exposed to wide temperature swings and harmful radiation due to being outside of the Earth’s protective ionosphere. It is crucial that any data path present be immune to these detrimental effects.
The introduction of galactic radiation can not only cause the onboard electronics to fail due to device degradation and single event latchup but can also lead to background radiation being coupled into the signal path as unwanted noise, degrading the signal to noise ratio. Unwanted …

A Secure Reconfigurable System-On-Programmable-Chip Computer System, William Herbert Collins
Masters Theses
A System-on-Programmable-Chip (SoPC) architecture is designed to meet two goals: to provide a role-based secure computing environment and to allow for user reconfiguration. To accomplish this, a secure root of trust is derived from a fixed architectural subsystem, known as the Security Controller. It additionally provides a dynamically configurable single point of access between applications developed by users and the objects those applications use. The platform provides a model for secrecy such that physical recovery of any one component in isolation does not compromise the system. Dual-factor authentication is used to verify users. A model is also provided for tamper …
The Characterization Of A Cmos Radiation Hardened-By-Design Circuit Technique, Austin James Womac
The Characterization Of A Cmos Radiation Hardened-By-Design Circuit Technique, Austin James Womac
Masters Theses
This thesis presents the analysis, implementation and testing of a circuit-level radiation hardened-by-design (RHBD) technique first presented in [1]. Radiation effects heavily influence the cost and design of electronics bound for radiation-rich environments such as in nuclear reactors or space. The circuit-level RHBD technique is presented as a cost-effective way to mitigate total-ionizing dose (TID) radiation in digital complementary metal-oxide-semiconductor (CMOS) transistor circuits. These claims are analyzed and experimentally tested.
Devices from a relatively old and a newer semiconductor fabrication process are tested to investigate the impact of device scaling on the RHBD technique’s effectiveness. A rad-tolerant frequency synthesizer that …
Advanced Studies On Locational Marginal Pricing, Yanli Wei
Advanced Studies On Locational Marginal Pricing, Yanli Wei
Doctoral Dissertations
The effectiveness and economic aspect of Locational Marginal Price (LMP) formulation to deal with the power trading in both Day-Ahead (DA) and Real-Time (RT) operation are the focus of not only the system operator but also numerous market participants. In addition, with the ever increasing penetration of renewable energy being integrated into the grid, uncertainty plays a larger role in the process of market operation. The study is carried out in four parts.
In the first part, the mathematical programming models, which produce the generation dispatch solution for the Ex Post LMP, are reviewed. The existing approach fails to meet …
Vehicle-To-Grid (V2g) Reactive Power Operation Analysis Of The Ev/Phev Bidirectional Battery Charger, Mithat Can Kisacikoglu
Vehicle-To-Grid (V2g) Reactive Power Operation Analysis Of The Ev/Phev Bidirectional Battery Charger, Mithat Can Kisacikoglu
Doctoral Dissertations
More battery powered electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs) will be introduced to the market in 2013 and beyond. Since these vehicles have large batteries that need to be charged from an external power source or directly from the grid, their charging circuits and grid interconnection issues are garnering more attention.
It is possible to incorporate more than one operation mode in a charger by allowing the power to flow bidirectionally. Usually, the bidirectional power transfer stands for two-way transfer of active power between the charger and the grid. The general term of sending active power from …
Conductive Textiles And Their Use In Combat Wound Detection, Sensing, And Localization Applications, Stephen A. Holland
Conductive Textiles And Their Use In Combat Wound Detection, Sensing, And Localization Applications, Stephen A. Holland
Masters Theses
Conductive textiles, originally used for electromagnetic shielding purposes, have recently been utilized in body area network applications as fabric antennas and distributed sensors used to document and analyze kinematic movement, health vital signs, or haptic interactions. This thesis investigates the potential for using conductive textiles as a distributed sensor and integrated communication system component for use in combat wound detection, sensing, and localization applications. The goal of these proof-of-concept experiments is to provide a basis for robust system development which can expedite and direct the medical response team in the field. The combat wound detection system would have the capability …
