Single MEXCCII-Based Grounded Immittance Functions Simulation and Applications.

A simple circuit based on modified extra-X second-generation current conveyor (MEXCCII), which is capable of realizing the following grounded immittance functions: a lossless capacitor, a lossy capacitor, a lossy inductor and a lossy frequency-dependent negative conductance, is introduced in this paper. The circuit employs one MEXCCII and three passive components. The use of single active block makes the circuit structure simpler. No component's matching constraint is needed in the proposed circuit. The nonideal study of the proposed grounded immittance circuit is also included. The circuit's performance is examined using 0.18- μ m technology-based PSPICE simulations. Experimental results which are performed using off-the-shelf integrated circuits (ICs) and bread board are also included. The proposed circuit is negligibly affected by the temperature variation and process variation. A single pole high-pass filter as an application of the realized lossy capacitor and a band-pass filter as an application of the realized lossy inductor are also presented in this paper. The realized filters offer the feature of ease of cascadability. [ABSTRACT FROM AUTHOR]
