摘要

提出了一种基于28nm数字CMOS的200 MS/s 2倍交叉14位流水线SAR ADC。该ADC采用了一种新型残留放大器,在低功耗下实现低噪声,并结合了交错通道时间常数校准。该ADC在200 MS/s时的峰值SNDR为70.7 dB,同时从0.9 V电源消耗2.3 mW。

A 70 dB SNDR 200 MS/s 2.3 mW dynamic pipelined SAR ADC in 28nm digital CMOS
We present a 200 MS/s 2x interleaved 14 bit pipelined SAR ADC in 28nm digital CMOS. The ADC uses a new residue amplifier for low noise at low power, and incorporates interleaved channel time-constant calibration. The ADC achieves a peak SNDR of 70.7 dB at 200 MS/s while consuming 2.3 mW from an 0.9 V supply.
