Novel Fractional order Universal Filter using model order reduction techniques

A unique Universal Filter utilizing the multi mode second generation current controlled current conveyors(MO-CCCII) and Model Order Reduction Techniques is proposed. The paper makes use of the model order reduction techniques for the design of filters. Any fractional-order filter can be made using a stationary phase element, also known as a fractional-order capacitor. It is suggested to use a fractional 0.2, 0.4-order filter. From reduced integer-order fractional differentiators, the fractional order capacitor was obtained by the Carlson method employing a third-order Foster I RC network circuit. The filter is tested and verified theoretically utilizing BJT-based MOCCCII and TINA Simulation. Results from comparisons with higher-order circuits show that filters implemented utilizing order reduction approaches produced comparable results with the original one.
