Comparative Study of Op-Amp-based Integrators Suitable for Fractional-Order Controller Design
In this paper, a fractional-order capacitor (FOC) of an order = 0.89 (i.e. constant phase angle –80.1 degree) was emulated via Valsa RC network with five branches. The network component values were optimized using modified ...
Validation of Fractional-Order Lowpass Elliptic Responses of (1 + )-Order Analog Filters
In this paper, fractional-order transfer functions to approximate the passband and stopband ripple characteristics of a second-order elliptic lowpass filter are designed and validated. The necessary coefficients for these ...
