Abstract
This work presents a new method to design the fractional-order linear phase filter based on the interior point algorithm. The transfer function of the fractional-order linear phase low-pass filter is derived from the general form of the fractional-order all-pole low-pass filter transfer function. The optimization problem of the phase-frequency characteristics of the fractional-order filter is modeled and solved. A detailed analysis of the stability and frequency domain of the optimized fractional-order linear-phase filters is presented. The active circuits for (1+α)-order filters are designed and simulated.
