This brief makes an important step forward on the ideas first presented in our earlier paper about the use of nonwhite chopping sequences for offset compensation in timeinterleaved analog-to-digital converters. More specifically, we present an adaptive system that takes advantage of nonwhite chopping in slowly nonstationary settings. Simulations show that by using this technique the estimation time and the signal-to-noise ratio are significantly improved with respect to white chopping.

Abstract

This brief makes an important step forward on the ideas first presented in our earlier paper about the use of nonwhite chopping sequences for offset compensation in timeinterleaved analog-to-digital converters. More specifically, we present an adaptive system that takes advantage of nonwhite chopping in slowly nonstationary settings. Simulations show that by using this technique the estimation time and the signal-to-noise ratio are significantly improved with respect to white chopping.
