Total Ionizing Dose Characterization of a Commercially Fabricated Asynchronous Fft for Space Applications
نویسندگان
چکیده
The total ionizing dose characterization of the radiation-hardened implementation of a novel architecture for high-performance, energy efficiency FFT engines is presented. Simulations and test chip measurement results indicate that a radiation-tolerant 1024-point FFT based on this architecture will achieve an efficiency of 120 nJ/Unit-Transform and 2 μs throughput. The proof-of-concept chip shows a total ionizing dose hardness of 1 Mrad (SiO2).
