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.
