Dual-mode comparator and analog to digital converter having the same |
摘要 |
A dual-mode comparator may include an object voltage input unit that generates a first current flowing through a first path and a second current flowing through a second path based on a first object voltage and a second object voltage, a current mirror unit that performs a current-mirror operation for the first path and the second path to output a comparison voltage at an output terminal, a bias unit that generates a bias current corresponding to a sum of the first current and the second current, and a mode switching unit that controls the current mirror unit to have a first structure in an auto-zero mode and that controls the current mirror unit to have a second structure in a comparison mode.
