Impact of Single-Event Transient Duration and Electrical Delay at Reduced Supply Voltages on SET Mitigation Techniques

Single-event transients (SETs) in 16-/14-nm bulk fin field effect transistor (finFET) logic chains have been measured using a custom-designed test IC. A variety of logic gate chains were designed, and SET pulse widths were obtained across a wide range of supply voltages. In light of the increased SET response at reduced supply voltages, the efficacy of filter-based mitigation is assessed by analyzing the voltage dependence of SET duration against the characteristic electrical inverter delay.
