Abstract :
A Z-domain two-port flowgraph synthesis method for switched-capacitor (SC) ladder filters is described. This approach for the design of lossless-dielectric-integrator (LDI) ladder filters is, compared to other methods, general and flexible. The proposed method can lead to a design of a locally nonreciprocal and globally reciprocal network. Both conventional switched-capacitor ladder filters and new switched-capacitor realizations can be designed using this approach. It is concluded that the advantages of these novel SC filter realizations can be exploited when the filters are implemented using integrated MOS technology.<>
