Abstract
A novel scheme using two internally compensated operational amplifiers with unmatched gain-bandwidth products is suggested as a replacement for the conventional single-amplifier integrators, inverters or summers. The scheme, while providing exact phase compensation, contributes to magnitude compensation as well. Filters realized using such a scheme have an extended range of frequency of operation with reduced error in pole frequency and in Q.Keywords
