摘要：

The　single　analog　filter　(SAF)　hybrid　filter　bank　(HFB)　ADC　is　presented　in　this　paper.　Base　on　SAF　architecture,　a　calibration　model　is　derived　to　integrate　the　analog　filter＇s　realization　errors　and　channel　mismatches　errors.　A　two-channel　SAF　HFB　ADC　with　12-bit　resolution　and　200MHz　sampling　rate　is　implemented.　The　experimental　results　show　that　the　average　spurious-free　dynamic　range　(SFDR)　over　the　whole　frequency　spectrum　enhanced　from　35　dB　to　88.3　dB　when　the　proposed　calibration　method　has　been　used.　©2010　IEEE.
