Abstract
An equalization method is provided for compensating for variations in the characteristics of individual analog-to-digital converters found in a time interleaved analog-to-digital converter circuit. One of a plurality of converters is chosen as a reference converter. Individual characteristics of the remaining converters are compared with the reference converter to provide differential responses therewith. The differential responses are equalized to provide compensation for variations in gain, offset, phase/frequency response, and timing found amongst the plurality of time interleaved converters.
