Nullor models of these elements are used to deduce a rule for transforming voltage-mode circuits with VFOAs to current-mode circuits with COAs. Low-pass and high-pass filters with COAs are designed and their functionality is verified by a computer modeling."@en . . "361774" . . "2008-04-23+02:00"^^ . . "Vrba, Kamil" . . . .
