Offset mismatch, gain mismatch, and sample-time error between time-interleaved channels limit the performance of time-interleaved analog-to-digital converters (ADCs). This paper focuses on the sample-time error. Techniques for correcting and detecting sample-time error in a two-channel ADC are described, and simulation results are presented.
