Abstract

This paper introduces a new active element combining the useful features of differential voltage, dual-X and first generation current conveyors. The new proposed active element is further utilized to introduce a new generalized filter topology employing grounded components only. The proposed single active element-based topology benefits from first-order and second-order filter realization by appropriate impedance specialization. The circuit topology with single current input provides two output currents and voltages in each case. A thorough study of proposed active element along with extensive simulations is carried out to validate the filter topology. A detailed non-ideal study is also given. To further support the usefulness of filter topology, higher-order filters are also realized. The new active element and the new filter structure provide advancement to the existing knowledge; with the scope of active element being further exploited for analog signal processing applications in general. The proposed differential voltage dual-X first generation current conveyor (DV-DXCCI) and its filtering applications are simulated using TSMC 0.25 \(\upmu \)m technology.
