Sažetak
In this paper the design procedure of unity-gain low-pass (LP) 2nd-and 3rd-order active resistance-capacitance (RC) filters is presented. The sensitivity of the filter’ s transfer function magnitude to the variations of both active and passive components is investigated. The design procedure for low passive sensitivity, LP 2nd-and 3rd-order class-4 Sallen and Key active-RC allpole filters, using impedance tapering, has already been published. On the other hand, the reduction of sensitivity to an active element is the subject of minimization of the Gain-Sensitivity-Product (GSP). In this paper we demonstrate the application of impedance tapering to the extreme bounds finally obtaining a unity gain filter. It is demonstrated that unity gain filters have reduced passive sensitivity to the highest degree, but increasingly high active sensitivity, with increasing pole Q-factors.
