Pipeline analog to digital converter and analog to digital conversion method

Abstract

A pipeline analog to digital converter includes converter circuitries. The converter circuitries are configured to sequentially convert an input signal to be digital codes. The converter circuitries includes a first converter circuitry and a second converter circuitry. The first converter circuitry is configured to a convert a first signal to be a first digital code in the digital codes, and generate a first residue signal according to the first signal and the first digital code. The second converter circuitry is configured to receive the first signal and the first digital code to quantize the first signal according to the first digital code, in order to generate a second digital code in the digital codes, and generate a second residue signal according to the first residue signal and the second digital code.
