Versatile multi-function universal voltage-mode filter

In this study, we introduce a versatile three-input three-output universal voltage-mode construction, which is comprised of only one differential difference current conveyor (DDCC), two differential voltage current conveyors (DVCCs) and four passive elements. It is highly flexible and easy to design. The application to the implementations of three-input single-output and single-input three-output universal filter functions has been presented. Both filter implementations exhibit the features of cascadability and insensitivity. HSPICE simulations are performed to demonstrate the results.
