Abstract

This work investigates power-efficient correction methods for ultra low-power time-interleaved SAR converters. First, analog techniques for gain and offset correction are proposed, and their impact on the overall power efficiency is analyzed. Furthermore, a layout technique for the intrinsic correction of time-skew errors in low-power converters is discussed. Finally, measurement results on a 5bit 1GS/s 16-channel time-interleaved SAR converter are reviewed.
