In this paper, a new CMOS high performance dual-X second-generation current conveyor (DXCCII) is presented. The proposed DXCCII provides good linearity, high output impedance at Z terminals, and excellent output input current gain accuracy. Besides the proposed DXCCII circuit operating at a supply voltage of +/- 1.5 V. Moreover, a tunable novel lossless frequency-dependent negative resistance (FDNR) circuit employing only a single active element and three passive components is firstly proposed in this study. The applications of the DXCCII and FDNR to realize a current-mode fifth-order elliptic filter are given. The proposed DXCCII and its applications are simulated using CMOS 0.35 mu m technology.
