MULTIFUNCTION N-PORTS DERIVED FROM GENERAL FLIEGE CIRCUIT

Kamil Vrba - Josef Cajka - Václav Zeman

   A general autonomous circuit derived from the Fliege filters is presented. The transformation of the above circuit into four multifunction networks is shown. The proposed networks can be used as second-order analog filters working in different modes . Simulation results illustrate the properties of the proposed networks.

Keywords: operational amplifiers, RC-active networks, analog filters
