Title: Left-LUD SC ladder filter with compensation for finite amplifier gain and offset voltage
Keywords: Filters, gain- and offset- compensation, operational amplifi

Abstract: An approach for reducing the effects of operational amplifiers finite dc gain A and offset voltage Vos in left-LUD SC ladder filters is proposed. The effectiveness of the proposed approach is demonstrated by designing a sixth-order bandpass elliptic SC filter. The variation of the finite gain A from its nominal value A0 is taken into account.
