Özet

In this work, a wideband and high-performance CMOS implementation of 2nd-generation current conveyor (CCII) is proposed. The proposed circuit is composed of a high performance voltage follower stage which is based on differential pairs to provide high voltage swings on input and output ports and a current follower stage. It is shown that the proposed voltage follower stage can be used to implement high performance 1st and 3rd-generation current conveyors (CCI and CCIII, respectively) that have very small equivalent impedances on ports X, high equivalent impedances on ports Y and Z and also high-valued voltage and current transfer bandwidths. 2nd and 3rd order filter circuits as well as a half-wave recti filer circuit are given to show the performance and usefulness of the proposed current conveyor circuits. The simulation and experimental results are given to verify the theoretical analyses.
