Abstract :
It is pointed out that the multiple-feedback topology for highorder active filters recently introduced by Perry, here labelled inverse f.l.f. (i.f.l.f.) topology, has significantly better dynamicrange properties than the otherwise equivalent `follow-the-leader-feedback¿ (f.l.f.) structure. The procedure for optimising the signal-level capabilities and the sensitivity performance of i.f.l.f. circuits is presented.
