Abstract
An analog-to-digital converter includes: a first input terminal to receive a first input signal; a second input terminal to receive a second input signal; a noise shaping module configured to compare the first input signal to the second input signal received, and to output a digital output signal and a residue signal in a first phase of a noise shaping operation; and a storage module configured to store the residue signal during the first phase of the noise shaping operation, the storage module configured to receive an analog input signal and remove the residue signal from the analog input signal in a second phase of the noise shaping operation to output a new first input signal to the noise shaping module.
