Design of First Order Cascadable All Pass Filter Using FDCCII

A single fully differential second-generation current conveyor (FDCCII) and grounded passive components, as well as two new cascadable voltage mode (VM) first-order all-pass (AP) filters, are proposed in this study. From a cascading point of view for voltage-mode circuits, all of the presented designs have the characteristics of higher input and lower output impedances. To evaluate the effectiveness of the filters and confirm the proposed theory, simulation results using the SPICE tool are used.
