Summary:
This paper proposes an approach for modelling noise due to fractional capacitor (FC) realized using domino ladder network. The proposed noise model has been applied in analyzing noise in fractional order (FO) Sallen-Key filter containing two FCs of different order. The output noise power spectral density of the FO filter has been calculated considering the noise contribution due to all the circuit components used for designing the filter. The theoretical analysis and simulation studies show that the noise contribution due to FCs changes with the change in the order of FCs. However, the change may not be significant in comparison with the overall noise level of the circuit.
