Designing of Fractional Order Inverse Chebyshev Low Pass Filter Using Particle Swarm Optimization

The design of fractional order inverse Chebyshev low pass filter has been presented in this paper. (1+α) filters have designed by comparing the transfer function notch with second-order filter. Particle swarm optimization utilized to derive coefficients fractional-order varying α from 0.1 0.9. canonical forms these realized using multiple input Biquad circuits. value circuit elements for each derived. Further, values equivalent RC ladder network constant phase element derived fifth-order continuous expansion orders 1.2, 1.5 and 1.8. magnitude plots 1.2 1.8 plotted SPICE plot compared PSO approximated confirm feasibility OP-Amp based a mean error 0.495dB.
