CCII based KHN fractional order filter

This work aims to generalize the analysis of the fractional order filter to work for the low-pass, band-pass and high-pass responses. So, general expression for the maximum and minimum frequency points and the half power frequency points will be derived. In addition, the effect of the transfer function parameters on the filter poles and hence the stability is introduced. Besides, the effect of the fractional orders on the frequency response will be presented. Finally, to verify the numerical analysis and the proposed design procedure, circuit simulation will be used.
