Abstract :
The paper reviews a circuit method of minimization of the influence of the unity gain frequency (f1) of the operational amplifiers (OA) on the main parameters of the RC-filter (of the selective amplifier, SA) with the Rauch´s architecture. It allows increasing the quasi-resonance frequency of SA (ωp), which is realized on OA, decreasing the dependence of ωp and filter quality factor Q upon f1.
