SECOND ORDER ACTIVE FILTERS Abstract of the Disclosure A family of second order active filters is described. A general form of the filter comprises an input terminal, an output terminal, and a common terminal, a first reactance and a resistance coupled in series between the input and common terminals, a first amplifier coupled from a connection point between the first reactance and the resistance to the output terminal, a first potential divider between the input terminal and one of the output and common terminals, a second amplifier coupled from a tapping point of the first potential divider via a second reactance to the connection point, a second potential divider between the output terminal the the common terminal, and a third amplifier coupled from a tapping point of the second potential divider via a third reactance to the connection point, at least one of the reactances being inductive and at least one other being capacitive. Different configurations are described for low-pass, notch, high-pass, band-pass, and all-pass filters, in some of which the first potential divider and second amplifier and second reactance, or the second potential divider and third amplifier and third reactance, are omitted.
