Abstract: A latch apparatus and applications thereof are provided. The latch apparatus consists of a latch circuit and a switchable DC block unit. The switchable DC block unit is coupled to the latch circuit, and configured to: isolate a cross-coupling path in the latch circuit and store a voltage difference before the latch apparatus performs the latching operation; and when the latch apparatus performs the latching operation, provide the stored voltage varying with time to increase the overdrive voltage of at least one transistor in the latch circuit (increase the transistor transconductance), so that the latch apparatus maintains high speed operation at low supply voltage.

Abstract: A latch, an operation method of the latch, and a comparator using the latch are disclosed. The latch includes first and second cross-coupled pairs and first and second transistor pairs. First terminals of the first and second current paths of the first cross-coupled pair are respectively coupled to first terminals of the first and second transistors of the first transistor pair. First terminals of the third and fourth current paths of the second cross-coupled pair are respectively coupled to first terminals of the third and fourth transistors of the second transistor pair. Control terminals of the third and fourth transistors are respectively coupled to the first and second current paths. Control terminals of the first and second transistors are respectively coupled to the third and fourth current paths.
