Abstract
A semiconductor integrated circuit device provided with a pipeline A-D conversion circuit in which the enhancement of accuracy and the reduction of power consumption are accomplished is provided. The pipeline A-D conversion circuit is connected in series with an input terminal to which an analog signal to be converted is inputted and has a plurality of stages. The stages other than the first stage connected with the input terminal through at least one stage, including the first stage that receives input signals from the input terminal are constructed as follows: each of the other stages is comprised of two or more sample and hold circuits and an amplifier connected in common with the two or more sample and hold circuits. The two or more sample and hold circuits are caused to perform interleave operation.
