With　the　development　of　the　electronic　information　industry,　integrated　circuit　package　design　for　high　integration　and　high　power　has　become　an　important　cornerstone　for　chip　function　enhancement　and　is　an　important　traction　for　all　technology　and　product　innovation.　However,　with　the　complexity　of　modules,　diverse　operating　environments,　and　complex　internal　harmonic　components　of　circuits,　noise　signals　have　seriously　affected　the　normal　operation　of　circuits.　Therefore,　this　paper　proposes　a　circuit　device　design　solution　suitable　for　filtering　noisy　signals　based　on　the　functional　analysis　of　LC　filtering　characteristics　during　the　design　of　integrated　circuit　packages.　Firstly,　the　filtering　principle　is　analyzed　based　on　the　filter　IC　and　the　comparative　analysis　of　the　packaging　materials　of　the　IC,　secondly,　the　circuit　model　is　established　and　the　principles　of　the　four　filtering　circuits　of　the　LC　filter　are　discussed,　finally,　the　finite　element　simulation　software　of　COMSOL　is　used　to　model　and　simulate　this　LC　filter,　the　simulation　results　have　a　high　match　with　the　simulated　response　of　the　model,　the　results　show　that　the　proposed　scheme　of　this　paper　The　results　show　that　the　proposed　scheme　can　effectively　filter　the　noise　signal　and　provide　theoretical　guidance　for　the　innovation　and　application　of　filtering　integrated　circuits.　©　2023　IEEE.
