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.

Claim (Index 11):
An analog-to-digital converter converting a single-ended analog input into digital representation, comprising:\n an input buffer, outputting a positive differential signal and a negative differential signal based on the single-ended analog input; and an analog-to-digital conversion module, receiving the positive differential signal and the negative differential signal to generate the digital representation, wherein: the input buffer further transmits a noise compensation signal to the analog-to-digital conversion module; the input buffer includes a differential-in and differential-out operational amplifier to form a circuit that generates the positive differential signal and the negative differential signal based on the single-ended analog input; and a first virtual ground terminal at a negative differential input terminal of the differential-in and differential-out operational amplifier and a second virtual ground terminal at a positive differential input terminal of the differential-in and differential-out operational amplifier are coupled to the analog-to-digital conversion module to provide the analog-to-digital conversion module with the noise compensation signal.
