Design Active Filter Based on Genetic Algorithm


The lossy-FDNR based active filter has an important property among manydesign realizations. This includes a significant reduction in componentcount particularly in the number of OP-AMP which consumes power.However the problem of this type is the large component spreads whichaffect the filter performance.In this paper Genetic Algorithm is applied to minimize the componentspread (capacitance and resistance spread). The minimization of thesespreads allow the filter structure to be integrated since the minimumcomponent spread mean minimum chip area required for fabrication.
