Background calibration of offsets in interleaved analog to digital converters

A multi-channel time interleaved ADC (TIADC) provides for offset estimation and correction. The correction is accomplished through analog adjustment of offset rather than by digital correction of their outputs. In certain aspects, polarity reversal circuits may be used to further improve performance...
