Gain- and offset-compensated modification of a sixth-order left-direct (IA) type wide bandpass SC ladder filter is proposed. It is based on the use of simple and fast operational amplifiers with low precisely known and stable dc gain A. The variation of the finite gain A from its nominal value A0 is taking into account.

PL

Przedstawiono metodę kształtowania wzmocnienia i kompensacji pełzania zera w szerokopasmowym SC filtrze drabinkowym szóstego rzędu. Wykorzystano proste i szybkie wzmacniacze operacyjne z małym, określonym i stabilnym wzmocnienie dc. Wzięto pod uwagę odchyłki wzmocnienia od wartości nominalnej.
