The invention provides a flip-flop. In one embodiment, the flip-flop receives a low swing clock signal, and comprises a first NMOS transistor, a first latch circuit, a second NMOS transistor, and a second latch circuit. The low swing clock signal is inverted to obtain an inverted low swing clock signal. The first NMOS transistor is coupled between a receiving node and a first node, and has a gate coupled to the inverted low swing clock signal. The first latch circuit is coupled between the first node and a second node. The second NMOS transistor is coupled between the second node and a third node. The second latch circuit is coupled between the third node and a fourth node, and generates an output signal on the fourth node.
