FGMOS-based differential difference CCCII and its applications

A novel floating gate MOS (FGMOS) transistor-based differential difference controlled current conveyor (DDCCC) is proposed in this paper. Major advantages of the FGMOS-based DDCCC are low power dissipation and simplicity. The proposed circuit is designed using only 14 MOS transistors. The total power dissipation of the proposed circuit is equal to 7.38 µW. The other advantage of this circuit is that intrinsic resistance seen at port X of the DDCCC can easily be tuned by a biasing current. The tuning range of the intrinsic resistance is rather wide. Additionally, a current controlled universal filter and tunable positive and negative active resistors are presented as applications of the proposed circuit. The DDCCC and its applications are simulated using SPICE in 0.18 µm CMOS technology
