ABSTRACT:
A sense amplifier-based flip-flop includes a first latch, a second latch, a floating reduction unit, an input signal applying unit, a ground switch and a delay reduction unit. The first latch outputs a signal to a first output terminal pair, and outputs an evaluation signal pair corresponding to an input single pair to the first output terminal pair. The second latch latches the evaluation signal pair and outputs the evaluation signal pair to a second output terminal pair. The floating reduction unit is controlled by signals of the first output terminal pair and is operationally connected between current passing nodes of the first latch to prevent the first output terminal pair from floating. The input signal applying unit is disposed between the current passing nodes and a ground terminal, and receives the input signal pair. The ground switch is disposed between the input signal applying unit and the ground terminal, and is controlled by the clock signal. The delay reduction unit is disposed between the input signal applying unit and the ground switch, and reduces a signal delay from when the clock signal to when the evaluation signal pair is output from the second output terminal pair.
