Abstract
A technique of offset averaging for reducing INL and DNL in flash and folding A/D converters is presented in this paper. The proposed method uses second-order active resistive networks implementing Gaussian-like spatial filters. Compared to previously reported methods employing passive resistive grids, a better offset reduction is achieved without sacrificing the signal gain. Both behavioral and transistor-level simulation results confirmed the performance of the proposed technique.
