Abstract
An analog-to-digital converter with noise elimination is disclosed. The analog-to-digital converter converts a single-ended analog input into digital representation, and comprises an input buffer and an analog-to-digital conversion module. The input buffer outputs a positive differential signal and a negative differential signal based on the single-ended analog input. The analog-to-digital conversion module receives the positive differential signal and the negative differential signal to generate the digital representation. The input buffer further transmits a noise compensation signal to the analog-to-digital conversion module. The noise compensation signal contains noise information about noise transmitted from the input buffer to the analog-to-digital conversion module through the positive differential signal and the negative differential signal. The analog-to-digital conversion module uses the noise compensation signal to compensate for the noise transmitted from the input buffer to the analog-to-digital conversion module through the positive differential signal and the negative differential signal.
