该论文提出了一款采用65nm CMOS工艺的2.4GHz Wi-Fi接收器，通过辐射硬化技术使其能够承受高达500kGy的总电离剂量，解决了核电站退役过程中极端辐射环境下无线通信的难题。测量结果表明，即使在500kGy剂量下，接收器仍能保持可接受的性能，验证了无线系统在极端辐射环境中的可行性。
Abstract This work presents a 2.4GHz Wi-Fi receiver in 65nm CMOS, designed with radiationhardened techniques to sustain operation under total ionizing dose to 500kGy. Such tolerance addresses the requirements of nuclear power plant decommissioning, where conventional studies have considered doses of only several Gy. Measurement results confirm that even at 500kGy, the proposed receiver maintains acceptable performance showing the feasibility of wireless systems in extreme radiation environments. Decommissioning operations at nuclear power plants have been steadily progressing; however, work in highly radiation environments, such as inside the nuclear reactor, remains extremely challenging for human operators. Consequently, the deployment of remotely operated robotic systems is indispensable. Currently, wired control using LAN cables is the predominant method for robot controls, but it imposes several limitations. Cables act as
