Abstract:This article presents three different higher‐order inverse filter (IF) configurations using current differencing buffered amplifier (CDBA) as an active component and a few passive elements. The topology can be used to synthesize fourth‐order inverse low pass filter (FO‐ILPF), inverse band pass filter (FO‐IBPF), and inverse all‐pass filter (FO‐IAPF) using suitable admittance combinations. PSPICE simulations verify the functionality of the proposed IFs with the CMOS‐based CDBA using 180 nm technology. The theore… Show more
