<p>The present invention relates to a multiplying digital analog converter, which is included in a pipeline analog digital converter and an operating method thereof. The converter includes: a first capacitor part to sample and hold an input voltage in a sampling phase, and to amplify a difference of the input voltage and a reference voltage and to transfer the voltage difference to an output terminal in an amplification phase; and a second capacitor part to sample and hold the input voltage in the sampling phase, and to transfer the voltage difference, in which the reference voltage is subtracted from the input voltage, to the first capacitor part in the amplification phase, wherein the first capacitor part includes three Y-connected capacitors.</p> |
