Abstract
A pre-charged high-speed comparator includes a first negative phase logic switch, a second negative phase logic switch, a third negative phase logic switch, a first positive phase logic switch, a fourth negative phase logic switch, a second positive phase logic switch, a third positive phase logic switch, a fourth positive phase logic switch and a fifth positive phase logic switch. The two output terminals of the pre-charged high-speed comparator is raised to a voltage roughly half of a source voltage so that the time required for a regeneration circuit that includes the third negative phase logic switch, the first positive phase logic switch, the fourth negative phase logic switch and the second positive phase logic switch to get into the transistor active region is shortened, thereby increasing the overall operating speed of the comparator circuit.
