Title:AnalysisandDesignofEfficientChipAreaReductionforCICDigitalFilter
Abstract:
Withthegrowingdemandforcompactandpower-efficientelectronicdevices,reducingthechipareahasbecomeacriticalaspectofintegratedcircuitdesign.Inthispaper,wefocusontheanalysisanddesignofaCascadedIntegratorComb(CIC)DigitalFilter,aimingtoeffectivelyreducethechipareawhilemaintainingitsfunctionalityandperformance.Weexploredifferenttechniquesandapproachestoachievethisgoal,takingintoconsiderationthetrade-offsbetweenareareduction,powerconsumption,andsignalprocessingrequirements.Theexperimentalresultsdemonstratetheeffectivenessofourproposeddesigninachievingsignificantchipareareduction.
