Abstract
A system and method for radiation-tolerant level shifting are disclosed. In some embodiments, an integrated circuit may include a plurality of level shifters, where each of the plurality of level shifters configured receive a same logic level in a first voltage domain and to output candidate logic levels in a second voltage domain, and where at least one of the candidate logic levels subject to being different from another one of the candidate logic levels. The integrated circuit may also include a voting circuit coupled to the plurality of level shifters, where the voting circuit is configured to evaluate the candidate logic levels and output a selected logic level based, at least in part, upon the evaluation.
