Abstract
An analog-to-digital converting apparatus includes a first stage converter which performs a first analog-to-digital conversion on an input analog signal during a first stage period, a second stage converter which receives a first residue from the first stage converter amplified by a first gain and which performs a second analog-to-digital conversion during a second stage period, and a recombination logic circuit which combines a first output signal from the first stage converter and a second output signal from the second stage converter into an output digital signal that corresponds to the input analog signal. The second stage converter generates a second stage feedback signal obtained by amplifying the second output signal by the first gain during a first sub-cycle in the second stage period, and generates a second output signal of a second sub-cycle subsequent to the first sub-cycle based on the second stage feedback signal.
