【摘要】 本文是根据振荡理论，用实验方法证实负阻抗变换器的潜在不稳定性，提出了负阻抗变换器的两种工作方式： １．稳定工作方式； ２．不稳定工作方式．同时指出，变换阻抗和产生振荡是负阻抗变换器的二种基本应用。 利用负阻抗变换器的不稳定工作方式可以获得ＬＣ串联和ＬＣ并联谐振，构成性能良好的正弦振荡器，有实用价值。更多还原

【Abstract】 This paper focuses on several aspects of NIC. Experiments based on oscil- latory theory confirm the potential instability of NIC. Both kinds of operating condition(stable and instable) have been examined. It is pointed out that impe- dance transform and oscillation are the two main applications of NIC. Taking advantage of the instable operating condition, we can obtain LC se- ties/parallel resonence. By the use of this method we can develope a satisfac- tory sinusoidal oscilltor for practical use.更多还原
