Noise analysis of fractional-order two-integrator CCII low-pass filter using Pspice

In this paper output noise is investigated for several fractional-order filters. Examples are given using the low-pass Butterworth current-mode active-RC filter approximations. It is demonstrated experimentally that as with integer-order filters, output noise decreases with decreasing order of fractional-order filters. The considered circuits use CCIIs and have two integrators in the feedback loop. The fractional-order filter has one fractional capacitance realized by a second Foster circuit. Other components are of integer order. The noise comparison is simulated with Pspice.
