Abstract:Single Event Functional Interrupt (SEFI) poses a severe threat to the normal operation of spacecraft. This paper investigates SEFI in Analog-to-Digital Converters (ADCs) with storage units using precision positioning of pulsed lasers. Based on the experiment, it was discovered that a bit flip in the configuration registers in ADCs results in changes in parameters such as digital filter frequency, operating mode, and gain, leading to an upward or downward offset of ADC output codes. Similarly, a bit flip in the… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
