Abstract

We present some new active-RC integrator and differentiator circuit schemes using the Current Feedback Amplifier (CFA) device. A multiplier element (ICL 8013) has been appropriately utilized in feedback/feedforward connection, to obtain electronic tuning of the circuit time constant (τo) by the d.c. control voltage (Vc) of the multiplier. Satisfactory test results on wave processing had been verified by with hardware implementation in the frequency range of 10 KHz ∼ 200 KHz, and also by PSPICE macromodel simulation.

电压控制积分器/微分器使用电流反馈放大器

采用电流反馈放大器(CFA)器件，提出了几种新的有源rc积分器和微分器电路方案。在反馈/前馈连接中适当地利用了一个乘法器元件(ICL 8013)，通过乘法器的直流控制电压(Vc)获得电路时间常数(τo)的电子调谐。通过在10 KHz ~ 200 KHz频率范围内的硬件实现和PSPICE宏模型仿真，验证了对波处理的满意测试结果。
