ANALOG-TO-DIGITAL CONVERTER AND LONG-TERM-EVOLUTION ADVANCED DEVICE AND METHOD FOR ANALOG-TO-DIGITAL CONVERSION

摘要

An analog-to-digital conversion that converts an input signal to an output signal by using multiple analog-to-digital converting circuits. A first analog-to-digital converting circuit generates a first signal based on the input signal and further outputs a feature signal of a first quantization error of the first analog-to-digital converting circuit. A second analog-to-digital converting circuit generates a second signal based on the input signal and the feature signal. The output combiner combines the first signal and the second signal to generate the output signal and thereby to reduce a quantization error factor in the output signal that is due to the first quantization error.
