Circuit-level simulations are performed to evaluate the radiation tolerance of the DAC. Simulations show that even though the DAC core circuit is immune to radiation effects, auxiliary circuits are highly susceptible to analog single-event transients (ASETs). Circuit-level mitigation techniques are addressed, resulting in a DAC that is estimated to be immune to 60 MeVcm2/mg SET. The total current consumption with 3.3 V supply is 0.58 mA at 1 MHz sampling frequency.enASETDACradiation tolerantSiGe BiCMOS technologySpace applicationsTIDComputer Science, Information and General Works::005: Computer Programming, Programs, Data and Security::005.1: ProgrammingConference Paper10.1109/PACET60398.2024.10497042Conference Paper
