Voltage Dependency of Propagating Single-Event Transient Pulsewidths in 90-nm CMOS Technology
This paper reports on the supply voltage dependency of single-event transient (SET) propagation and multinode charge collection phenomena in integrated circuits. We have found that the SET pulsewidth propagating to subsequent stages in a circuit may decrease with reduced power supply voltage, which runs
counter to the general conclusion that ultralow power applications are much more susceptible to disruption from a particle strike. This effect provides the circuit designers a guidance to reconsider
the impact of voltage on SET pulsewidth. Index Terms—Multinode charge collection, single-event transient
(SET), subthreshold, ultralow power voltage.
