Abstract :
Single-event upsets are studied in digital logic cells in a radiation-hardened CMOS SOI technology. The sensitivity of SEU to different strike locations and hardening approaches is explored using broadbeam and focused beam experiments. Error distributions in chains of logic flip-flops are studied to determine the impact of various cell designs and hardening techniques on upset uniformity.
