A new approach to the long –appeared problem is considered. The single Op-Amp high-order ARC filters use 2 to 8 times less number of Op-Amps compared to other type ARC filters of the same order. This design pro-vides lower power consumption (important for portable devices, geophysical “in-the-field” or underwater instru-ments), as well as simpler network and technology. Fun-damentally important is the capability of these filters to operate at very high interference level in stop-band, what may be crucial in certain problems of instrumentation. Fil-ters represented below are considered from this point of view. The procedure of the design of certain filters is briefly presented and illustrated with examples.
