提出了一种用于DC-DC变换器的抗辐射控制器。辐射加固电路通常用于空间应用。综述了体CMOS集成电路的辐射效应，以及抗辐射设计技术。功率转换器的约束和权衡进行了讨论，并介绍了最先进的耐辐射电流模式控制器的开关电源实现。该控制器采用AMS0.35 μ mCMOS工艺集成，并采用ELTMOS管进行抗辐射加固。对制造的IC进行测试，证明其功能。
This work presents a radiation hardening controller for a DC-DC converter. Radiation hardening circuits are used typically in space applications. An overview of the radiation effects on bulk CMOS integrated circuits, as well as, the design techniques required for radiation tolerance are presented. Power converter constraints and trade-offs are discussed and the state-of-the-art radiation tolerant current mode controller for switch mode power supplies implemented is described. The controller was integrated in AMS 0.35μm CMOS technology and uses ELT MOS transistors for radiation hardening. The fabricated IC was tested proving its functionality.
