Abstract
his paper presents an SRAM (Static Random-Access Memory) based flexible radiation monitor. The monitor was fabricated in a 65 nm CMOS technology, it was designed as application-specified integrated circuit, which comprises 768K bits SRAM cells matrix with individual power supply and a digital control core with SPI interface. By adjusting the core voltage of the SRAM matrix, the radiation sensitivity was made flexible. Also, SRAM cells with different threshold voltage were implemented to get further extension on tunable sensitivity range. The monitor has been tested under heavy ions with an LET(Linear Energy Transfer) from 1.5 to 48.5 MeV∙cm2/mg, high-energy (50-186 MeV) and low-energy (0.7-5 MeV) protons, 14-MeV and thermal neutrons. An analysis was performed on how Single-Event Upsets sensitivity changes while tuning the supply voltage under different radiation environments. The results show that the monitor have the potential for space and facility applications.
