摘要：

In this work a data acquisition system, based on a design diversity redundant scheme, is tested under total ionizing dose effects. The data acquisition system is composed by three ADCs and two voters, implementing different levels of diversity (architectural and temporal). This system is implemented on a 130nm commercial mixed-signal programmable SoC (PSoC 5), from Cypress Semiconductor. The system was tested under Co-60 gamma radiation with a dose rate of 1 krad(Si)/h reaching a total dose of 242 krad(Si). One of the system copies presented a significant degradation on its linearity during the irradiation, while the others kept the functionality with less severe degradation, evidencing the advantage of using diversity to improve resilience in mixed-signal redundant systems.
