Abstract :
Using a time-interleaved A/D converter is one method of obtaining a Nyquist-rate A/D converter from delta-sigma (ΔΣ) A/D converters. In this paper, it is shown that the performance of the time-interleaved ΔΣ A/D converter is as good as other forms of parallel ΔΣ A/D converters. The issue associated with the gain mismatch among the channels is addressed with a proposed solution to circumvent the channel matching problem
