ANALYSIS OF VARIOUS TOPOLOGIES OF FDCCII AND ITS APPLICATIONS

In this paper, various topologies of fully differential second-generation current conveyor (FDCCII) are presented. The proposed blocks are useful in mixed-mode applications where fully differential signal processing is required. The FDCCII combines the advantages of both second-generation current conveyor (CCII) and differential difference amplifier (DDA), which is further utilized to realize Universal Biquad filters. The circuit can operate from low supply voltages down to 1.65 V. The characteristics of the proposed circuits are verified by LTSPICE simulators using TSMC CMOS 0.35-µm technology.
