Eliminating Measured Radiation Effects to Go for FM-Level Mixed Signal Design
摘要
By further optimizing the radiation hardness, the radiation effects that were measured in the first prototype of our 180 nm X-FAB ASIC flight model were mitigated or even completely eliminated. These effects include a fatal drift during total dose and single event transients on analog outputs and a cumulative destructive event when irradiated with high-energy particles. We describe developed measurement setups, test results, methods of analysis and the solutions found for the issues.
