Designing cellular parasitic-insensitive SC-ladder filters suitable for mask-programmable manufacture
A.W. Kälin, R.P. Sigg, G.S. Moschytz · Electronics Letters · 1986
A systematic design technique for the well known LDI equivalent SC-ladder filter is described. The proposed scheme starts from an R-LC prototype that is specially synthesised for active SC simulation. Based on this prototype, our approach systematically leads to an SC realisation with identical loop cells. These are well suited for implementations where regular structures are desirable, such as mask-programmable filters.
