A synthesis procedure for the realization of a general voltage transfer function without real
axis zeros using a single fixed gain amplifier, an one-port and one RC two-port has been …

An operational transconductance amplifier (OTA) and an operational amplifier are being
used to synthesize various second‐order cascadable active RC filters. Two of them are …

A method is described for synthetising active RC filters by using the subtraction property of
differential operational amplifiers. The differential operational amplifiers used have infinite …

A systematic-realisation technique of the 2nd-order active-R filter using an inherent amplifier
pole is proposed. To realise such a filter it is shown that two operational amplifiers and three …

A general characterization of second-order active-RC filters employing one, two, and three
operational amplifiers is given. When certain conditions are met, it is shown that the desired …

A canonical structure of an RC active filter is presented which can realize any transfer
function. It consists of a fixed passive part and an active part that is computed from two …

Active filters can be designed using operational amplifiers with resistors as the only external
components. The reactance of these filters is derived from the parasitic capacitances …

ABSTRACT A new synthesis procedure is formulated for RC-active filters. It involves the use
of idealized unity-gain current and voltage amplifiers as the active clement. To realize a pair …

Active filters can be designed using only resistors and amplifiers as the circuit elements. The
reactance for these filters is obtained from the parasitic capacitances associated with the …
