Abstract
Methods and apparatus for blind detection and correction of interleaving errors using all-digital processing of data output by multiple sub-ADCs of a time-interleaved ADC are disclosed. The methods and apparatus detect and correct frequency-dependent timing and gain mismatches of the sub-ADCs of the time-interleaved ADC using a novel multiple-input multiple-output (MIMO) filter structure. Additionally, a novel adaptive sampling frequency hopping scheme is proposed to achieve uninterrupted data conversion by the time-interleaved ADC during transient time of ADC clock frequency switching.
