Abstract: As a crucial elementary course for electronic and communication engineering majors, analog circuit experiment course fills the gap between the analog circuit fundamental and the practice. To address the issues in curriculum construction, an analog circuit experiment case with confidentiality characteristic is designed in this paper, including system solution, implementation scheme, hardware circuit and teaching content, etc. This experiment teaching case revolves around the confidentiality education, and involves nearly entire typical application circuits of integrated operational amplifier in analog circuit curriculum, and has a high malleability to ensure the learning initiative of student in diverse levels, and contributes to cultivating students' capacity of decomposing complex circuit systems and solving complex engineering problems, and is closely associated with other courses of the electronic information engineering and the communication engineering majors to help student to construct an overall understanding of the curriculum system, which could provide an entire scheme for the analog circuit experiment teaching as well as a thought for the experiment case design.
