Abstract

This paper focuses on experimental teaching in high-frequency electronic circuits, conducting research using small-signal amplifiers and capacitive-feedback oscillators as case studies. For the small-signal amplifier, a circuit is constructed using an experimental box, and tools such as a sweep frequency generator and an oscilloscope are employed to measure indicators like its amplitude-frequency characteristics and amplification factor, while analyzing the impact of the collector load on its performance. Regarding the capacitive-feedback oscillator, a circuit is designed using simulation software to investigate the effects of parameters such as the feedback coefficient and load resistance on the oscillation frequency, start-up time, and output voltage. The experimental results demonstrate that rational parameter design can optimize circuit performance, providing both theoretical and practical references for experimental teaching in high-frequency electronic circuits.
