Abstract：

This　paper　studies　the　error　of　the　hybrid　filter　banks　(HFB)　due　to　analog　realization　errors.　It　is　shown　that　the　architecture　of　HFB　is　much　more　sensitive　to　even　small　analog　imperfections.　Therefore,　the　performance　of　HFB　has　a　dramatic　deterioration.　In　order　to　improve　the　performance,　a　method　named　Central　Frequency　is　presented.　The　results　show　that　the　value　of　max　aliasing　function　the　main　restricting　source　of　resolution　in　HFB　ADC　(analog-to-digital　converter)　decreases　about　50dB.　And　the　SNR　(signal-to-noise　ratio)　of　the　whole　system　is　enhanced　above　30dB.　©　2008　IEEE.
