Timing skews in time-interleaved analog-to-digital converter (ADC) (TIADC) greatly degrade the spurious-free dynamic range of the TIADC, which can be improved effectively by digital compensation algorithms. Literature review shows that many nonblind compensation algorithms required the accurate timing skew parameters measured before the compensation process. In this paper, the blind timing skew estimation (TSE) for the TIADC system is investigated. With the evaluation of the working rationale… CONTINUE READING
