Catalog of Realizations for DXCCII using Commercially Available ICs and Applications

This paper presents fifteen distinct practical realizations for dual-X second generation current conveyor (DXCCII) using commercially available integrated circuits. Detailed comparisons and results are presented to verify, the utility of proposed realizations. The catalog of proposed realizations is a first attempt and is expected to be useful for testing newly developed circuits based on dual-X second generation current conveyor. Each of the first fourteen proposed realizations uses four ICs. One three IC based implementation is further given making the total count fifteen. Some additional features are also explored which further enhance the versatility of DXCCII The paper further presents a novel and compact quadrature oscillator to verify the applicability of the proposed realizations. Single resistance control of the frequency of oscillation is also demonstrated by employing the new gain-variable DXCCII. Experimental results are also included along with simulation results to validate the proposed theory and its practical significance.
