In this paper, interdependency between differentialmode (DM) and common-mode (CM) signals in fully-differential (FD) Gm-C filters is investigated. It was found that although DM signals are signals of interest in FD circuit, CM signals have nonnegligible influence on the DM signals and vice versa. Based on the perturbation concept and state-space(More)
In this paper, a novel structure of fully-differential doubly-terminated ladder Gm-C filter is proposed. The proposed structure can be classified as another variation of the recently proposed alternative structure, which has much better linearity performance than the traditional Gm-C filter structure. Simulation results show that the proposed filter(More)
