Abstract：

This　paper　studies　the　error　of　the　hybrid　filter　banks　(HFB)　due　to　analog　realization　errors.　Small　errors　have　a　dramatic　influence　on　the　aliasing　and　distortion　functions　of　HFB.　The　performance　deteriorates　with　the　error　of　analog　devices　growing.　The　simulations　show　that　the　aliasing　and　distortion　errors　based　on　power　complementary　pairs　(PCP)　are　much　lower　than　conventional　HFB　ADCs＇.　The　value　of　the　aliasing　errors　decreases　above　50　dB　as　well　as　the　distortion　errors　decreases　about　2　orders.　To　prove　the　feasibility　of　PCP　HFB,　A　simulation　system　of　12　bits,　1Gsps　is　realization.　©　2008　IEEE.
