High Temperature Cmos Silicon Carbide Asynchronous Circuit Design, Landon John Caley

Graduate Theses and Dissertations

Designing a digital circuit to operate in an extreme temperature range is a challenge with increasing demand for a solution. Large variations in temperature have a distinct impact on electron mobilities causing substantial changes to the threshold voltage of the devices. These physical changes affect the setup and hold times of clocked components, such as D-Flip Flops, of a traditional synchronous digital circuit. Focusing primarily on high temperature circuit operation, this dissertation presents a digital circuit design methodology pairing an asynchronous circuit design paradigm called NULL Convention Logic (NCL) as well as traditional Boolean circuitry with a wide-bandgap semiconductor material, …
