Abstract
Disclosed herein are systems and methods that describe a noise-shaping (NS) SAR architecture that can be simple, effective, and low power. In an aspect, a method includes the operation of receiving a first analog input; determining a first digital output based on the first analog input; obtaining a first quantization error for the first digital output; integrating the first quantization error; receiving a second analog input; and determining a second digital output based on the summation of the second analog input and the first integrated quantization error to perform noise-shaping.
