摘要：

This　paper　presents　an　adaptive　semiblind　background　calibration　of　timing　mismatches　in　an　M-channel　time-interleaved　analog-to-digital　converter　(TIADC).　By　using　a　sine　wave　testing　signal　and　an　extra　sub-ADC,　the　relative　timing　errors　for　all　sub-ADCs　can　be　calculated　accurately　and　immediately　without　interrupting　the　normal　operation　of　TIADC.　The　estimated　timing　errors　can　be　corrected　in　a　fixed　structure　simultaneously.　The　proposed　calibration　method　allows　wide　bandwidth,　less　restrictions　on　input　signal　and　fast　estimation.　Simulation　results　demonstrate　the　effectiveness　of　the　proposed　estimation　and　correction　techniques.　©　2015　IEEE.
