A new CMOS dual-X second generation current conveyor (DXCCII) with an FDNR circuit application

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 ZZ terminals, and excellent output–input current gain accuracy. Besides the proposed DXCCII circuit operating at a supply voltage of ±1.5V. 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 0.35μm technology.
