A new CMOS realization of a four terminal floating nullor (FTFN)

A novel circuit configuration for the realization of a four terminal floati ng nullor in CMOS technology is proposed. The circuit proposed combines the advantages of a cascade of common-source and common-gate amplifiers and a floating current source. PSPICE simulations show that the proposed circuit is suitable for wideband, accurate and wide dynamic range current-mode sign al processing. The feasibility of the circuit is also tested successfully i n a current-mode band-pass filter structure.
