Abstract
A differential comparator is provided. The comparator receiving two differential signals and generating a comparison result represented by an output signal on one of two output terminals respectively on two current paths. The comparator comprises two pairs of latch transistors respectively disposed on the two current paths and two pairs of input transistors respectively disposed on the two current paths, wherein gates of the latch transistors on one of the current paths are commonly coupled to the output terminal between the latch transistors on the other current path, gates of the input transistors on one of the current paths respectively receives an input signal of one of the differential signals and a reference signal of the other differential signal and each of the input transistors is disposed between the output terminal and one of the latch transistors on the current path thereof.
