Single op-amp high-order CT polynomial ARC LP-filter

A new approach to the long-appeared problem is presented. The single op-amp high-order ARC filters use 2 to 8 times less number of op-amps compared to other types of ARC filters of the same order. This design provides lower power consumption, which is especially important for portable devices, such as geophysical "in-the-field" or underwater instrument, as well as simpler network and technology. Fundamentally important is the capacity of these filters to operate at very high interference signal ratio in stop-band, which may be crucial in certain problems of instrumentation. The procedure of the design of certain type of filters is presented and illustrated with examples. The hybrid thin-film integrated filters are fabricated inn Scientific & Research Institute GIRICOND (St. Petersburg, Russia).
