abstract: This thesis describes the design of a Single Event Transient (SET) duration measurement test-structure on the Global Foundries (previously IBM) 32-nm silicon-on insulator (SOI) process. The test structure is designed for portability and allows quick design and implementation on a new process node. Such a test structure is critical in analyzing the effects of radiation on complementary metal oxide semi-conductor (CMOS) circuits. The focus of this thesis is the change in pulse width during propagation of SET pulse and build a test structure to measure the duration of a SET pulse generated in real time. This test structure can estimate the SET pulse duration with 10ps resolution. It receives the input SET propagated through a SET capture structure made using a chain of combinational gates. The impact of propagation of the SET in a >200 deep collection structure is studied. A novel methodology of deploying Thick Gate TID structure is proposed and analyzed to build multi-stage chain of combinational gates. Upon using long chain of combinational gates, the most critical issue of pulse width broadening and shortening is analyzed across critical process corners. The impact of using regular standard cells on pulse width modification is compared with NMOS and/or PMOS skewed gates for the chain of combinational gates. A possible resolution to pulse width change is demonstrated using circuit and layout design of chain of inverters, two and three inputs NOR gates. The SET capture circuit is also tested in simulation by introducing a glitch signal that mimics an individual ion strike that could lead to perturbation in SET propagation. Design techniques and skewed gates are deployed to dampen the glitch that occurs under the effect of radiation. Simulation results, layout structures of SET capture circuit and chain of combinational gates are presented. / Dissertation/Thesis / Masters Thesis Electrical Engineering 2017
