Design of Standard Cell for Anti-radiation
With the advancement of the aerospace industry, the reliability of integrated circuits that can overcome the impact of the radiation environment continues to increase. In this paper, two kinds of radiative effects of integrated circuits are focused on the total ionizing dose effect and the single-event latch-up effect. In response to these two effects, the anti-radiation reinforcement technology of the logic gate standard cell was adopted at the corresponding design level. The design of the schematic and the circuit simulation are performed, including transient simulation and static simulation in this paper. In addition, the standard cell’s logic information is verified and integrated into the standard cell library. A guard ring is designed on the layout of the standard cell so that it has radiation resistance. The layout of the standard cell is abstracted and the file containing the standard cell physical information is exported. The verification results and physical information of the standard cell demonstrate that the proposed technique can achieve the effect of anti-radiation.
