Modelling and optimization of active filters by hybrid VIV-MMC-graphs


Novel “VIV” signal flow graphs are introduced. They provide a description of active filter subblocks consisting of OpAmps with grounded inputs. The Tow-Thomas, the Åckerberg-Mossberg, the Fleischer-Tow, and MFB structures are typical representatives of such a filter class. Many kinds of active filter like the Sallen-Key utilize a more general OpAmp… (More)
