In this paper, the concept of "Fractional order" element is reported. RC ladder network itself behaves as a fractional order element which is developed and the same ladder network is been used in Integer order differentiator and integrator circuit to make it "Fractional Order Differentiator" (FOD) and "Fractional Order Integrator" (FOI) circuit. The performance of FOD and FOI using RC ladder network is studied in both frequency & time domain. Same response is then compared with the performance of Integer order differentiator and integrator circuit. The simulation of FOD and FOI is done using NI Multisim 12.0 software.
