Realization of KHN and Tt Filters Using Ddccta Block

Abstract

A new active building block for analog signal processing, namely, Differential Difference Current Conveyor Transconductance Amplifier (DDCCTA) provides the possibility of inbuilt electronic tuning of the parameters of the analog function circuits to be implemented. This block is modified and the performance is checked through PSPICE simulations. A modified block is utilized to realize the KHN and TT filters. The proposed realizations use three DDCCTA for the KHN filter and only one DDCCTA for the TT filter circuit. Also, the resulted realizations are tested via PSPICE simulations.
