CCCDBA based implementation of voltage mode third order filters

Abstract

In the present paper implementation of third order low pass, high pass filters have been proposed by using current-controlled current differencing buffered amplifier (CCCDBA). In the present work, an effort has been made to simulate the third order doubly-terminated LC ladder low pass filter, third order doubly-terminated LC ladder high pass filters using CCCDBA. Here, in each circuit more than one CCCDBA and few grounded capacitor without have been utilized. The designed circuits are very suitable for integrated circuit and very easy in implementation. The circuits' performance is simulated through PSPICE and its simulated results obtained so is comparable to the theoretical one. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.
