Realization of series and parallel R-L and C-D impedances using single differential voltage current conveyor

In this paper, realization of series and parallel R-L immitances using differential voltage current conveyor (DVCC) is presented. The proposed circuits enable actively simulation series and parallel R-L and (-R)-(-L) immitances. Applying RC:CR transformation to the proposed configurations, series and parallel C-D and (-C)-(-D) simulators can also be realized with the same topology. They employ single DVCC and at most three resistors and one capacitor. No component matching constraints are imposed for the realisations. The performance of the proposed immittance simulators is demonstrated on both a second-order voltage and second-order current-mode filters. PSPICE simulations are given to verify the theoretical analysis.
