Systematic synthesis of R-L and C-D immittances using single CCIII

We present a systematic approach to the synthesis of R–L (resistor–inductor) and C–D (capacitor–frequency-dependent negative resistance) configurations by using a single third-generation current conveyor (CCIII) and a minimum number of passive elements. All the simulated immittance values can be orthogonally adjusted, there are no requirements for any certain element matching or cancellation constraints. The test filter circuits, constructed with the derived R–L immittances, are used to verify the theory by HSPICE simulations. The simulation results corroborating all our theoretical predictions are incorporated in the work. This methodology can be extended to the immittance synthesis based on different active elements.
