<p>PROBLEM TO BE SOLVED: To provide a pipeline type A/D converter for which the pair propriety of an amplifier is not required.SOLUTION: A first sample/hold circuit 40 of a B type converter UCB samples a first interpolation voltage Via_B and a second interpolation voltage Vib_B by time division from a converter in a preceding stage. A first sub-converter 42 divides a voltage between the first interpolation voltage and the second interpolation voltage into a plurality of segments, and generates digital data indicating the segment to which a predetermined common voltage is belonging. A first shift voltage generation part 44 generates an upper side shift voltage Vma' in a fourth phase, and generates a lower side shift voltage Vmb' in a fifth phase. A first amplifier 46 amplifies the upper side shift voltage Vma' in the fourth phase, and amplifies a lower side shift voltage Vmb' in the fifth phase.</p> |
