Stability analysis of fully-differential active-RC filters with common-mode feedback network

Abstract

In this paper, stability analysis of fully-differential active-RC filters with common-mode feedback (CMFB) networks connected at either the input and output terminals of the fully-differential op amps is presented. The results of such analysis, which were confirmed by simulation results, would enable the trading-off during the design process of the fully-differential active-RC filters to be more effective.
