摘要
PURPOSE: A dual mode comparator and an analog-to-digital converter having the same are provided to change in structure according being in an auto zero mode or a comparison mode and to constantly maintain a current.;CONSTITUTION: A current mirror unit(140) operates a current mirror on a first and a second path. The current mirror unit outputs a comparison voltage through an output terminal. A bias unit(160) generates a bias current corresponding to the sum of a first current and a second current. A mode switching unit(180) determines which current mirror unit has a first structure in an auto zero mode. The mode switching unit determines which current mirror unit has a second structure in a comparison mode.;COPYRIGHT KIPO 2013
