ABSTRACT:
The present invention aims to provide a pipeline type A/D converter capable of realizing low power consumption while preventing a reduction in feedback factor of an amplifier. One embodiment of the present invention is of a pipeline type A/D converter which converts an analog signal to a digital signal, including a plurality of stages coupled in tandem and an error correction circuit which generates the digital signal, based on sub digital signals respectively outputted from the stages. When a sub digital signal of N bits is outputted at at least one of the stages in the pipeline type A/D converter according to the one embodiment of the present invention, the stage gain of a transfer function becomes 2N−K−1, the number of returns becomes 2N−2 and an integer K has a relation of 1≦K≦N.
