A novel CMOS implementation of a four-terminal floating nullor (FTFN) is proposed. The presented FTFN circuit is based on two translinear cells and cascode current mirrors. It provides an alternative solution to differential amplifier-based FTFN circuits. Simulation results show that the proposed circuit is quite suitable for wideband, accurate and wide dynamic range current-mode signal processing. The feasibility of the circuit is tested on a current-mode bandpass filter structure.
