Abstract :
This paper aims at investigating the impact of non-white chopping on the offset compensation performance of time-interleaved analog-to-digital converters. The theoretical framework for selecting optimal chopping sequences is given allowing fast offset compensation and good spectral shaping. Both the signal-to-noise ratio and the spurious-free dynamic range are improved significantly.
