Performance study of fractional order integrator using single-component fractional order element

A single-component fractional order element (FOE) is realised and its performance is compared with the conventional FOEs such as cross resistance-capacitance (RC) ladder network and domino ladder network in the analogue domain. The single-component FOE is a capacitive-type probe coated with a porous film of poly-methyl-methacrylate (PMMA) and is dipped in polarisable medium. The fractional exponent of the fabricated single-component FOE and domino ladder can be varied between 0 and 1 whereas that of cross RC ladder realised in this work is 1/2. The performance of fractional order integrator (FOI) using these FOEs is studied in both frequency and time domain by simulation and experimentation. A comparative analysis of the performance of FOI is carried out.
