With the development of satellite communications, On-Board Processing (OBP) obtains more and more attentions due to the increased efficiency and performance. However, the large amounts of digital circuits in the OBP transponders are sensitive to the high-energy particles in space radiation environments, which may cause various kinds of single event effect. Among these effects, Single Event Upset (SEU) is the major potential reason for the instability of the satellite communication systems. Triple Modular Redundancy (TMR) is a classical and effective method for mitigating the SEU in digital circuits.
