Design Features of the Second-Order Active Band-Pass Filters with Independent Adjustment of Critical Parameters

Nowadays, it is urgent to develop a new generation of active RC filters, which allow for independent tuning of the critical parameters. This makes it easier to build new devices. The paper considers the generalized architecture of a new population of active RC band-pass filters (ARCFs) in which the independent adjustment of the critical parameters in the pass band is possible. As an example the equations for the transfer functions and their coefficients for two new ARCF modifications are given, which allow for the parametric synthesis of the definite design solutions. The results of modeling in the Micro-CAP program are discussed, confirming the advantages of the ARCFs of the considered family.
