科研反哺教学模式下《射频集成电路设计》课程教学改革与实践——以GaAs Sub-GHz高精度移相器芯片设计为例

Teaching Reform and Practice of the “RF Integrated Circuit Design” Course under the Research-Informed Teaching Model—Taking the Design of a GaAs Sub-GHz High-Precision Phase Shifter Chip as an Example

摘要: 作为微电子与集成电路工程教育的核心高级课程，《射频集成电路设计》(RF IC Design)传统教学普遍面临理论抽象、教学案例脱离工业界前沿、学生缺乏高频工程直觉等核心挑战。本文提出了一种基于“科研反哺教学”的项目驱动式教学改革路径。该方案以一款发表于行业前沿、基于0.15-µm GaAs工艺的6位Sub-GHz宽带数字控制移相器芯片为贯穿式核心教学案例。通过将“电感复用拓扑”“等效带通网络(EBP)”以及“主辅电感协同调谐”等科研创新点转化为阶梯式实训模块，引导学生在全面仿真与多维工程权衡中深化对高频底层逻辑的理解。实践表明，该模式有效消解了理论与实践的代差，显著提升了学生的工程综合实践能力与学术创新思维。

Abstract: As a core advanced course in microelectronics and integrated circuit engineering education, the traditional teaching of “RF Integrated Circuit Design” (RF IC Design) commonly faces pain points such as abstract theory, teaching cases disconnected from the industrial frontier, and a lack of high-frequency engineering intuition among students. This paper proposes a project-driven teaching reform path based on the “research-informed teaching” model. This approach adopts an industry-leading 6-bit Sub-GHz broadband digitally controlled phase shifter chip, based on a 0.15-µm GaAs process, as the overarching core teaching case. By translating scientific research innovations—such as the “inductor-reuse topology,” “equivalent bandpass network (EBP),” and “main-auxiliary inductor collaborative tuning”—into progressive practical training modules, the course guides students to deepen their understanding of underlying high-frequency logic through comprehensive simulation and multidimensional engineering trade-offs. Practice shows that this model effectively bridges the disconnect between theory and practice, significantly enhancing students’ comprehensive engineering practical abilities and academic innovative thinking.
