%X A new design method is presented for designing FTFN(Four-Terminal Floating Nullor)-RC filter of arbitrary order with signal flow graph. A FTFN-RC configuration that can be used to realize arbitrary order transfer function is obtained by direct analysis of network function. The filter circuit which contains n active elements, n grounded capacitors and resistors can produce nth order low-pass, band-pass and high-pass filters without changing the internal structure of circuit. So the circuit is simplified and integrated conveniently. PSPICE simulation at the MOS transistor level is carried out and results show that the proposed circuit is feasible.
