Abstract：

This　paper　presents　a　flexible　frequency-dependent　equivalent　model　(FDEM),　which　can　be　used　to　calibrate　the　nonlinear　errors　of　HFB.　Then,　a　two-channel　12　bits　200Msps　HFB　ADC　prototype　is　implemented.　The　validity　and　feasibility　of　the　proposed　method　is　verified　by　making　use　of　analyzing　the　output　data　of　the　actual　HFB　system.　The　experimental　results　show　that　the　average　spurious-free　dynamic　range　(SFDR)　over　the　93%　whole　frequency　spectrum　(7%　over-sampling)　is　enhanced　obviously　when　the　proposed　calibration　method　has　been　used.　©　2010　IEEE.
