Utilizarea convertoarelor de impedanţă în filtre active

Abstract

Active filters have a basic device of electronic communication equipment. In this paper we analyze the cheme of the impedance converter for two variants of realization. It is estimated sensitivity of the input impedance of the impedance converter to change the impedance converter component values. It shows that the sensitivity of simulated input impedance converter to each element of the active impedance converter does not exceed the sensitivity of passive RLC filter characteristics from nominal of the passive components R, L and C.
