Ideally differential-mode (DM) DC gain of a fully-differential (FD) ladder active-RC filter is 0.5 (or -0.6 dB). However in practice, due to limited gain of op amps, such a gain is always less than 0.5. In this paper, analysis of the DM DC gain of FD ladder active-RC filter is presented in which the result is simplified such that it can be used more conveniently.
