Voltage/current-mode universal filter using single FDCCII

This paper presents a new voltage/current-mode universal filter using single fully differential second generation current conveyor (FDCCII). The topology can be realized both voltage and current-mode filters such as low-pass, band-pass, high-pass, band-stop and all-pass filtering functions without changing circuit topology. The circuit employs one FDCCII, two capacitors and two resistors. The performance of proposed circuit is confirmed using PSPICE simulations with a standard 0.35 \mum CMOS process.
