Abstract(in English) | We compare the soft error tolerance of conventional flip-flops (FFs) and the proposed radiation-hard FF with small area, delay and area overheads by adding transistors and wires in a 130 nm process by using device simulation. Circuit simulations cannot evaluate layout dependence of soft errors. By constructing layout structures on TCAD, the layout dependence is evaluated. The critical LET of the proposed circuit becomes 2.5x larger than the conventional FF and the cross section of the proposed circuit is decreased to 30%. The correlation coefficient of the soft error tolerance on a specific condition between the measurement results and the circuit simulation results is 0.34, while that between the measurement results and the device simulation results becomes 0.74. |
