Current filters designed using a controlled current conveyor CCC

Abstract

The main task of that paper consists in the solution to some problems of active frequency filtering of current signals. The RC-active current filters of the first and the second order, designed using a second generation current conveyor CCII±, have been presented. Those filters of the second order designed using only one CCII±, without positive feedback, have a quality factor≤1/2. Because of that authors have proposed a new model of an amplifier - a Controlled Current Conveyor CCC. The proposed structures have been tested by means of the stimulation programme PSpice using macromodels of the CCC.
