ABSTRACT:
Systems and methods for synchronizing an input signal with a substantial mitigation of race conditions and a substantial increase in resolving time are provided. One embodiment includes a system comprising a first latching device configured to latch a first output signal from the input signal and a delay element configured to receive the first output signal and output a delay signal that is a delayed version of the first output signal. The system also includes a pass-gate element configured to receive the first output signal and to output a second output signal in response to a logic state of the delay signal. The second output signal has a delayed input edge without a delayed resolving edge. The system can be configured to force the first output signal to a stable logic state in response to the first output signal having a metastable state.
