A Unity-Gain Buffer Assisted Noise-Shaping SAR ADC Based on Error-Feedback Structure
文献摘要：
The passsive noise-shaping successive ap-proximation register(NS-SAR)analog-to-digital convert-er(ADC)demonstrates high performance in resolution improvement,power reduction,and process scaling,while its charge-sharing loss and limited bandwidth weaken the noise-shaping effect.This paper presents a first-order NS-SAR ADC based on error-feedback(EF)structure to realize high-efficiency noise shaping.It employs a lossless EF path by using a set of ping-pong switching capacitors with passive signal-residue summation technique.The proposed first-order EF NS-SAR prototype can be pro-moted to multi-order structure with the minor modifica-tion.Verified by simulation in 65-nm CMOS process,the proposed 9-bit NS-SAR ADC consumes 183.66 μW when operating at 20 MS/s with the supply voltage of 1.2 V.At the oversampling ratio of 16,it achieves a peak signal-to-noise-and-distortion ratio of 81 dB,yielding Schreier fig-ure of merit of 176.32 dB.
