In this paper, a new current mode fractional order filter is presented using multi-mode second generation current controlled current conveyors (MO-CCCII).in this method consists of two resistors and grounded capacitors using 3MO-CCCII. This is accomplished with a fractional-order capacitor, also known as a stationary phase element, to form a fractional-order filter. The proposed filter is designed as fractional 0.2, 0.4 orders. The fractional order capacitor was obtained using reduced integer-order models of fractional differentiators using the Carlson method18 using third order Foster I RC network circuit. The filter is simulated using BJT-based MO-CCCII using LTSPICE Simulation for the filter to verify the theory and show its performance of it.
