THE GENERALIZED CURRENT CONVEYOR GCCII IN THE ACTIVE FREQUENCY FILTERING OF CURRENT SIGNALS

摘要

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