Summary :

Optimum topologies for the realization of symmetrical bandpass filters with minimum capacitors and minimum opamps are proposed. The derivation of them is largely based on some important results of the GVCS synthesis proposed previously by the author. Design equations for the realization of fourth, sixth and eighth order elliptic bandpass filters are presented in detail and generalized to high order synthesis. Finally the low sensitivity property of the proposed topologies is demonstrated through design examples. Furthermore, some suboptimum topologies, which design equations are much simpler than that for the corresponding optimum topologies, are also presented.
