标题： WIP: Turning Fake Chips into Learning Opportunities

摘要： 这项进行中的论文介绍了一个案例研究，其中在一门初级电子课程中发现的假冒TL074运算放大器成为了一次实践学习体验的基础。假冒集成电路（IC）日益常见，对本科生电子实验室的完整性构成了重大威胁。我们没有简单地更换假冒元件，而是将这一问题转化为教学机会。学生们参与了实际的诊断工作，测量电流、分析波形并进行故障排除。通过使用假芯片组件，他们对模拟电路、供应链安全和实际工程有了更深入的理解。 显示英文摘要

摘要： This work-in-progress paper presents a case study in which counterfeit TL074 operational amplifiers, discovered in a junior level electronics course, became the basis for a hands on learning experience. Counterfeit integrated circuits (IC) are increasingly common, posing a significant threat to the integrity of undergraduate electronics laboratories. Instead of simply replacing the counterfeit components, we turned the issue into a teaching moment. Students engaged in hands-on diagnostics measuring current, analyzing waveforms, and troubleshooting. By working with fake chip components, they gained deeper insight into analog circuits, supply chain security, and practical engineering.
