Abstract

To fulfill upcoming communication specifications, it has become popular recently to employ pipelined-SAR architectures, incorporating residue amplifiers (RA) to achieve high resolution, wide bandwidth, and low-power ADCs [1, 2]. Hence, the RA design plays an important role in the ADCs. In this work, a distributed averaging correlated level shifting (DACLS) ringamp is proposed to not only enhance the resolution by reducing the RA gain error, but also extend the bandwidth by minimizing the RA output load compared to prior arts [2 - 4]. In addition, a customized bypass-window backend for the last pipeline stage is applied for power reduction.
