Integrator and differentiator with time constant multiplication using current feedback amplifier

A set comprising an active RC integrator and differentiator with time constant multiplication is presented. The proposed integrator and the differentiator can be used for low-frequency signal processing applications. Moreover, no extremely large-valued passive components are needed. In the integrator, the unlimited multiplication of time constants is allowed. Both have been implemented using commercially available current feedback amplifiers. Experimental results demonstrate the theoretical predictions.
