Abstract-- In this paper, an alternative CMOS realization of
an FTFN with a rail-to-rail input stage is proposed. Input stage
of the presented circuit is based on a three-times current mirror
to realize lowered gm deviation within the whole common-mode
input range. Output stage of the FTFN is constructed with using
active-feedback cascode current mirrors to obtain higher output
resistance at the output nodes Z and W. The performance of the
proposed FTFN structure is simulated with a novel grounded
inductance simulating topology with applying on a third-order
high-pass filter. All simulation results are given using SPICE
simulation program.
