Abstract	The case of implementation of current-mode filters is revisited using the concepts of transposed networks, and nullator-norator representation for active devices. Employing these principles, it is shown that a voltage-mode filter implemented using an ideal operational amplifier (OA) can be very easily converted to a current-mode filter using the same OA, when the OA is configured as a three-terminal inverting amplifier. In this article, we present the theoretical basis of our work and illustrate the technique using simulation and lab-bench filter models. The current-mode filters have the same frequency response and sensitivity properties as the associated voltage-mode filters.
