Fractional Order Inverse Filters using Current Feedback Operational Amplifiers and its application in Bio-medical Instrumentation

Abstract

In this paper, current feedback operational amplifiers (CFOAs)-based fractional order inverse filter is proposed. A new configuration of fractional order inverse filters (FOIF) is presented to realize inverse low pass, high pass and band pass filters in fractional order domain. The proposed configuration of fractional order inverse filters has been simulated in PSPICE using AD844 type CFOAs to validate the theoretical propositions. It’s utilized to remove the artifacts present in biomedical signal.
