This paper focuses on the teaching and practice of Fundamentals of Analog Electronics under the background of “New Engineering” education and the development needs of electronic information disciplines. By integrating device principles, amplifier circuits, and high-sensitivity magnetic detection systems, the study aims to enhance students’ learning interest and innovation ability. Starting from PN junctions, diodes, and optoelectronic devices, their applications in communication and magnetic field detection are introduced to bridge theory with practice. The principles of field-effect transistors and transimpedance amplifiers are then analyzed, including the effect of temperature on device performance and circuit gain. In the experimental section, an embedded control and data processing system based on LabVIEW is designed to achieve displacement control, signal acquisition, and imaging, combined with digital filtering to suppress interference. This work not only enriches classroom teaching but also provides a practical platform for nondestructive testing, weak signal extraction, and low-noise circuit design.

摘要

This paper focuses on the teaching and practice of Fundamentals of Analog Electronics under the background of “New Engineering” education and the development needs of electronic information disciplines. By integrating device principles, amplifier circuits, and high-sensitivity magnetic detection systems, the study aims to enhance students’ learning interest and innovation ability. Starting from PN junctions, diodes, and optoelectronic devices, their applications in communication and magnetic field detection are introduced to bridge theory with practice. The principles of field-effect transistors and transimpedance amplifiers are then analyzed, including the effect of temperature on device performance and circuit gain. In the experimental section, an embedded control and data processing system based on LabVIEW is designed to achieve displacement control, signal acquisition, and imaging, combined with digital filtering to suppress interference. This work not only enriches classroom teaching but also provides a practical platform for nondestructive testing, weak signal extraction, and low-noise circuit design.
