摘要 本文提供测量隧道二极管伏安曲线二次微商与直流偏压关系的谐波分析法。着重讨论测量原理,电路设计和误差对结果的各种影响。同时,指出进行这项工作对隧道二极管应用和它的物理性质研究的意义。文中介绍了典型测量结果。并对隧道二极管作低电平检波器应用的价值作了一些定量的讨论。 Abstract An instrument for measuring the first and second derivatives of l-V characteristics of tunnel diodes and point contact diodes as a function of D.C. bias was designed. The principle of operation is based on the harmonic analysis of the current. The circuit involved is rather simple. As an example for the application of this instrument, plots of first and second derivatives of a tunnel diode and a point contact diode were shown. From the given results, it has been pointed out that tunnel diodes may be used in low level detectors. 作者及机构信息 徐元华 1. 复旦大学 Authors and contacts HSU YUAN-HUA 1. 复旦大学 参考文献 [1] 施引文献
