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 …

Modeling And Control Of Single Phase Grid-Tie Converters, Bradford Christopher Trento

Masters Theses

The penetration of renewable energy into the electric utility grid is growing worldwide. At the heart of these renewable sources is the power electronic systems used to convert the renewable source to an output that can be connected to the grid. In recent years, there has been a great deal of work in designing converters for grid-tie applications and is continuing to grow. With recent smart grid activities, it is not likely that this work will cease in the short term. Most of the recent research is in ancillary services that the converter can offer in addition to the normal …
