一种负阻抗变换器的特性研究及其应用

The Characteristic Study and Application of One Type of NIC

对一种由运算放大器电路构成的负阻抗变换器（ＮＩＣ）做了较详细的研究，给出了该电路在开路、负载以及它与电阻做串、并联联接时的各种直流特性的理论分析和实验结果．实验结果与理论分析一致．最后给出了几种由ＭＩＣ构成的正弦振荡器电路，以及这种电路的调示特点及方法．

This paper focuses its notice in studing one type of NIC which is composed of operational amplifier. All the theoretic analyses and experimental data of the property of DC whilethe circuit is in opening,loading,and series or parallel connecting with resistor are given. The expeiment result is consist with the theoretic analyses. Finally,some sinusoidal oscillator consist ofNIC and adjusting method are supplied.
