A New Current Mode Multiplier Using Single CCCII Without Passive Components

摘要

A current mode multiplier is a valid structured block in many signal processing operations, such as modulation and demodulation schemes in communications, in development of bio-medical equipments, in analog computations, and fuzzy logic controllers. A single second generation current controlled conveyor (CCCII) based current mode multiplier without passive components is designed. CCCII has the eccentricity of intrinsic resistance in between the two input ports which are tunable by the external bias current. PSPICE simulator is utilized to examine the proposed design. The topology yields a simple structure and highly suitable for monolithic IC fabrication. Simulation results are confirmed with a voltage requirement of ± 2.5 V, the non linearities, total harmonic distortion (THD), and power dissipation are anticipated. Comparison of the proposed design with the existing methods is also performed. The parametric sweep and temperature analysis are also determined. The simulated results very well agree with the theoretical expectancy.
