Abstract: A sense amplifier includes a differential input circuit, a floating prevention circuit, and a differential amplifier. The differential input circuit output a first current flowing through a first node according to a first input signal, and second current flowing through a second node according to a second input signal. The floating prevention circuit outputs a third current flowing through the first node according to the second input signal, and fourth current flowing through the second node according to the first input signal. The differential amplifier generates a first output signal according to the first current or the third current flowing through the first node, and a second output signal according to the second current or the fourth current flowing through the second node. The sense amplifier may be coupled to a latch to form a flip-flop circuit.

Abstract: A signal receiving device may not need to consider jitter characteristics of a received signal by including a transition detecting device which receives first to third input signals having different signal levels for each unit interval, compares whether a signal level of a first differential signal, which is a differential signal between the first input signal and the second input signal among the first to third input signals, is greater than a first reference signal level to output a first comparison signal, and compares whether the signal level of the first differential signal is greater than a second reference signal level different from the first reference signal level to output a second comparison signal, and a clock data recovering device which recovers a clock signal embedded in the first to third input signals on the basis of the first and second comparison signals to output the recovery clock signal.
