The proposed cell has multiple working modes which can be used in different situations. Each part of the cell can be verified easily and completely by using different modes. This cell has been designed under an SMIC 0.13 μm process and 3-D simulated by using Synopsys TCAD. Heavy-ion testing has been done on the cell and its counterparts. The test results demonstrate that the presented cell reduces the cell＇s saturation cross section by approximately two orders of magnitude with little penalty on performance.展开更多
文摘This paper presents a radiation hardened flip-flop with an annular gate and a Muller C-element. The proposed cell has multiple working modes which can be used in different situations. Each part of the cell can be verified easily and completely by using different modes. This cell has been designed under an SMIC 0.13 μm process and 3-D simulated by using Synopsys TCAD. Heavy-ion testing has been done on the cell and its counterparts.
