    Second-Order Filters with Independent Setting and Adjustment of Basic Parameters
    (КПІ ім. Ігоря Сікорського, 2023) Antypenko, R. V.; Kyrpatenko, I. M.; Movchanyuk, A. V.; Fesich, W. P.
    A new topology of the second-order low-pass filter containing three operational amplifiers is proposed. As known, a feature of second-order filters based on operational amplifiers is the interdependence of the main filter parameters, such as the pole frequency, Q factor and gain. The second-order filters synthesized by the state variable method have the smallest relationship between the main parameters, but they also do not allow independent adjustment of the gain and Q factor, and contain at least three operational amplifiers. The proposed low-pass filter topology also contains three operational amplifiers and provides the possibility of independent setting of the pole frequency, Q factor and gain, as well as the possibility of independently adjustment of the Q factor and gain. Relationships have been obtained that relate the pole frequency, Q factor and filter gain to the nominal values of the passive filter elements. On the basis of these ratios, the possibility of independently changing the Q factor and gain of the filter is shown. On the basis of this topology, a second-order universal filter was synthesized with the possibility of independent setting and adjustment of the main parameters. A cut-off filter with independent installation and adjustment of the main parameters is also offered. Examples of second-order low-pass filter calculations and simulation results are given, which confirm the correctness of the calculations. Also, the results of modeling universal and rejection filters are given.
