摘要 针对 PN 结器件特性实验项目的拓展与延伸,采用数字锁相放大器设计了一个综合性物理
实验教学项目———PN 结器件静态噪声电压测量与噪声功率分析实验。首先,采用锁相放大器 OE1022D
测量了零偏压下的 PN 结型稳压二极管静态噪声电压 R 值,并计算了平均噪声功率 P av 。然后,采用扫
频法,逐点手动测量了 0.1 Hz 到 102 kHz 范围内多个频率点下的稳压二极管噪声电压,并计算求得各频
率点对应的平均噪声功率 P av ,得到其噪声功率谱函数 S( f) 。最后,详细分析了 S( f) 的频率特性,并分
析解读了闪烁噪声、热噪声和散粒噪声在频域的典型特征。该实验项目在近代物理实验、物理实验创新
竞赛、科研训练等环节中进行了教学实践与应用探索,有效地提升了学生在半导体材料、器件、噪声与物
理性能及其相互关系方面的理解和认知。

Abstract: Here,we design a new physics experiment project focusing on the noise characteristics of PN
junctions by using the lock-in amplifier,which can be used in the physics experiment education courses,
undergraduate research projects,innovation training,competition projects,etc. With the lock-in amplifiers
OE1022D,a systematic static noise voltage measurement was performed on the typical Zener diode under a
condition of zero bias voltage,ranging from 0.1 Hz to 102 kHz at several selected inner reference frequencies.In
addition,the noise power calculating methods were also discussed,followed with a systematic analysis on the
frequency-dependent noise characteristics.This project underwent teaching practice and exploration in modern
physics experiments,physics experiment innovation competitions,and research training,effectively boosting
students' understanding and cognition on semiconductor materials,devices physics,noise,performance,physical
properties,and their interrelationships.
