摘要

本文比较了几种用于可调谐应用(滤波器、振荡器、放大器等)的电子电阻控制方法。模拟(PSpice)和实验测试的基本J-FET晶体管的可调电阻，光耦合器，以及更先进的有源解决方案使用有源器件(可变增益放大器，电压模式乘法器)进行，以了解可用的线性范围，可调范围和预期的频率特征。

Comparison of Simple Design Methods for Voltage Controllable Resistance

This paper compares several ways of electronic resistance control for tunable applications (filters, oscillators, amplifiers, etc.). Simulation (PSpice) and experimental tests of basic J-FET transistor-based adjustable resistor, optocoupler as well as more advanced active solutions using active devices (variable gain amplifiers, voltage-mode multiplier) are performed in order to see available linear range, readjustability range and expected frequency features.
