Novel Cascadable All-Pass/Notch Filters Using a Single FDCCII and Grounded Capacitors

Abstract

Four new second-order voltage-mode cascadable all-pass/notch filters are proposed using only a single active element and four passive components. The active element used is a fully differential current conveyor. All the circuits possess highinput and low-output impedance, which is a desirable feature for voltage-mode circuits. A non-ideal and parasitic study is also performed. The proposed circuits are verified through PSPICE simulation results. © 2010 Springer Science+Business Media, LLC.
