Radiation-Hardened Delay-Insensitive Asynchronous Circuits For Multi-Bit Seu Mitigation And Data-Retaining Sel Protection, John Davis Brady

Graduate Theses and Dissertations

Radiation can have highly damaging effects on circuitry, especially for space applications, if designed without radiation-hardening mechanisms. Delay-insensitive asynchronous circuits inherently have promising potentials in mitigating the effects of radiation due to their delay insensitivity. This thesis proposes the use of two delay-insensitive asynchronous logic architectures to mitigate the effects of up to two single-event upsets (SEU) and a single-event latch-up (SEL). The multi-bit SEU mitigation with SEL protection architecture improves the original design by providing more integrity against data corruption and lock-ups caused by multi-bit SEUs, and it is expanded to simultaneously provide protection against SEL. The multi-bit SEU …
