IEEE JSSC副编辑毫米波CMOS射频电路VLSI
▸毫米波CMOS技术：通过创新的器件设计和工艺优化，实现了高频段（60GHz以上）信号的高效生成与处理，显著提升了集成度与能效比，适用于5G通信和雷达系统。
▸射频与微波电路：提出新型低噪声放大器（LNA）和混频器拓扑结构，在保持低功耗的同时将线性度提高30%，解决了毫米波频段信号链的噪声累积问题。
▸器件建模与电磁学：开发了基于物理的紧凑型器件模型，支持THz频段的精确仿真，误差率较传统模型降低50%，为高频IC设计提供可靠工具链。
▸能效优化与数字VLSI：采用自适应电压调节和近阈值电路技术，在40nm工艺下实现动态功耗降低65%，适用于物联网边缘计算芯片的能效关键场景。
