研究方向：生理信号感知前端芯片设计；传感器前端集成芯片设计；通用型模拟/数模混合芯片设计；轻量化人工智能数字芯片设计
学生要求：
1）对于模拟/数模混合芯片及传感器集成前端芯片领域，要求：熟悉集成电路设计相关理论基础及软件使用，包括Cadence virtuoso等；
2）对于面向生理感知、轻量化人工智能芯片及系统领域，要求：信号处理、人工智能相关理论基础及相关软件使用，数字集成电路设计基础、Verilog及python等；
3）最重要的要求：成绩没那么重要，不满足要求1和2但有其他的能看到科研潜力亮点的同学也非常欢迎。这个课题组看中人品端正、拥有足够的对科研的自驱力、以及善于交流和团结合作的能力。
（加一点解释：这个课题组觉得，本科成绩或者考研成绩在这里仅作为本科阶段学习能力的基本考量，是对做科研的基础加成而非保障，研究生阶段需要对技术有足够的热情和耐性；同时，没有足够的自驱力，朝十二晚五，很难在未来的激烈竞争里……）
随时更新的备注：抱拳拱手，25级研究生坑位早已满，后续有变化会随时更新。欢迎对这些研究领域感兴趣并打算在课题组读研的本科同学随时联系；
博士名额有，但限于满足前述要求，同时能力出色（有较好文章发表优先考虑）的同学，欢迎联系。
