Abstract
A modular approach for realizing various kinds of linear filters based upon different types of nonlinear transconductors is proposed. By using this ap proach, traditional Gm-C filter structures can be readily transformed into log-domain and other related kinds of filters with linear transfer characte ristics. The synthesis and realization of the proposed filters are demonstr ated and the simulation results given.
