Abstract-A new on-chip Single Event Transient (SET) test structure has been developed that can autonomously measure the width of random SET pulses. Simulation results show measurement granularity of 900 ps for a 1.5 µm technology and 65 ps for 0.13 µm technology. Laser tests were used to obtain experimental data on test chips fabricated using 1.5 µm process. Experimental measurements show pulse widths varying from 900 ps to over 3 ns as the laser energy is increased.Index Terms-Single event transient (SET), transient pulse width

Purpose Much of the extant research, practice and policy in engineering education has focused on the limited persistence, waning interest and lack of preparation among Black students to continue beyond the post-secondary engineering pipeline. However, this research suggests that many Black PhD students persist and succeed in engineering, fueled by various motivational strengths. To better understand the motivations of Black students in engineering doctoral programs, this study aims to explore the factors that influence their decision to enroll in either an engineering or a computing doctoral program. Design/methodology/approach This paper uses an intrinsic and extrinsic motivational framework to investigate the inspiration of 44 Black engineering doctoral students in PhD engineering programs in 11 engineering schools across the country. Findings Results show that the participants’ motivation to pursue a PhD in engineering comes from several distinct factors, including the following: an unyielding passion for their particular discipline, a sense of responsibility to serve marginalized peoples and society, a path toward autonomy, pre-PhD mentorship and research opportunities and family and prior work experience. Research limitations/implications Based on this study’s findings, a reconceptualization of graduate engineering education that incorporates the importance of “being Black” and its relationships with motivating and, potentially, retaining Black science, technology, engineering and mathematics (STEM) students is also offered. Originality/value This paper seeks to expose particular constructs and behaviors surrounding Black students’ motivation to learn and achieve in engineering at the highest academic levels, offering a more nuanced perspective than currently is found in traditional engineering education literature.
