Loveless, Thomas Daniel (2009-08-27)Department: Electrical EngineeringA reliability concern of growing interest in the microelectronics community is the deleterious effect of ionizing radiation. The so-called "single events" – single particles which can penetrate semiconductor material ...
-
Holt, Christopher (2008-04-23)Department: Electrical EngineeringDynamic logic circuitry is generally faster and smaller than equivalent static logic circuits. The use of these circuits in space is desirable, but not much work has been performed in assessing their vulnerability to the ...
-
Maharrey, Jeffrey Alan (2014-05-13)Department: Electrical EngineeringSingle event transients (SET) have become increasingly important to characterize since operating frequencies have surpassed 100 MHz. A common way to characterize SETs for a specific technology is to measure the range of ...

Olson, Brian David (2010-12-16)Department: Electrical EngineeringAnalog-to-digital converters (ADCs) are necessary circuits in many space, military, and medical circuit applications. Intelligence, surveillance, reconnaissance, and communication missions all require high performance ...
-
Casey, Megan Colleen (2009-12-21)Department: Electrical EngineeringWith decreasing feature sizes, transistors are being added to ICs in consistently greater numbers, which is leading to dramatic increases in power consumption. Changing process parameters and redesigning circuits are ...
-
Gaspard, Nelson Joseph III (2017-03-17)Department: Electrical EngineeringAlpha, heavy-ion, neutron, and proton experimental results from 130-nm to 28-nm technology nodes are establish single-event upset cross section trends in soft and hardened flip-flop designs. Trends show that at any LET ...
-
Shetler, Kevin Joseph (2016-04-11)Department: Electrical EngineeringA voltage reference is a critical component of analog and mixed signal systems because it provides a global signal used for a variety of system functions. The precision of a voltage reference is critical, so it must be ...
-
Blaine, Raymond Wesley (2014-04-29)Department: Electrical EngineeringModern systems-on-chip (SOCs) must incorporate high-performance analog and mixed-signal (A/MS) circuits with digital systems onto a single chip. This integration necessitates that these A/MS circuits be designed at advanced ...
-
Blaine, Raymond Wesley (2011-04-18)Department: Electrical EngineeringBias circuits (e.g. current sources) provide essential global signals in analog and mixed-signal design. Ideally, a bias circuit should be invariant over operating conditions such as temperature, output load, and supply ...
