摘要

K.W. Nay和a . Budak(1983)提出了一种利用jfet和运算放大器获得电压控制的正/负电阻的技术，具有宽动态范围和低失真。本文提出了两种新的运算放大器- jfet结构，它们不仅可以实现压控电阻，而且与Nay结构不同，还可以实现压控电感和压控电容元件。实验结果验证了理论公式的实际有效性。>

Realization of voltage-controlled impedances

K.W. Nay and A. Budak (1983) presented a technique employing JFETs and op-amps for obtaining voltage-controlled positive/negative resistance exhibiting wide dynamic range and low distortion. Here two new op-amp-JFET configurations are proposed, which not only realize voltage-controlled resistances but, unlike the Nay configuration, make it possible to realize voltage-controlled inductance and voltage-controlled capacitance elements, too. Experimental results are given to demonstrate the practical validity of the theoretical formulations. >
