摘要
The present invention relates to a multiplying digital analog converter included in a pipelined analog digital converter, and an operating method for same. The multiplying digital analog converter comprises: a first capacitor unit which samples an input voltage in a sampling phase and holds same, and amplifies the difference between the input voltage and a reference voltage in an amplification phase, and transmits same to an output terminal; and a second capacitor unit which samples the input voltage in the sampling phase, and holds same, and transmits, to the first capacitor unit, the voltage difference resulting from the reference voltage having been subtracted from the input voltage in the amplification phase. The first capacitor unit can comprise three Y-connected capacitors.
