Abstract

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