摘要：

Two new op-amp-based multifunction filter structures are proposed which can realize fractional order inverse low pass, high pass and band pass filters. In the first configuration, op-amp is used in an inverting mode while in the second structure op-amp is employed in non-inverting mode. To the best knowledge of the authors, any fractional order inverse filter structure employing any active element/device has not been reported in the open-literature so far. The proposed inverse filters have been simulated in PSPICE using mu A741-type op-amp as well as in MATLAB to validate the theoretical propositions.
