Abstract
An AD converter capable of achieving both an improved processing speed and a reduced circuit area in good balance. The AD converter pipelines analog-to-digital conversion by using a two-stage configuration consisting of a first conversion unit, or the prior stage, and a second conversion unit, or the subsequent stage. The first conversion unit is a conversion unit of noncyclic type. The second conversion unit is a conversion unit of cyclic type. The second conversion unit is given a conversion processing speed higher than that of the first conversion unit so that the second conversion unit performs cyclic processing twice while the first conversion unit performs conversion processing once.
