ABSTRACT:
A synchronizer circuit comprises a Schmitt trigger circuit which sharpens the rise or fall of an asynchronous input signal, and a clocked flip-flop circuit which converts the asynchronous signal having the sharpened waveform into a synchronous signal. In another embodiment, complementary asynchronous input signals having a large transition time are supplied to an RS flip-flop circuit in a first repeated interval in synchronism with a first clock pulse. Then, the state of the flip-flop is caused to remain stable in the other intervals. Subsequently, the output of the flip-flop is read out in synchronism with a second clock pulse by a transfer-gate field effect transistor. Thus, the asynchronous input signal is converted to a waveform-shaped and synchronized signal.
