Summary:
Two controlled current conveyors (CCCII) with positive and negative current transfers are described. The electrical characteristics of these two conveyors (current transfer, voltage transfer and parasitic impedances…) were determined. A controlled current amplifiers based on these two current conveyors are analyzed. PSPICE simulation results shows that the conveyor with negative current transfer (CCCII-) presents interesting characteristics compared to the conveyor with positive transfer (CCCII+). A comparison between the proposed amplifiers and the current amplifier described in [1] is presented. The latter confirms the improvement brought by our amplifiers at the level of the wide range of adjustability of the gain, and bandwidth observed.
