Abstract: 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 $\mu $W. 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 $\mu $m CMOS technology.
