Abstract
The disclosure concerns asynchronous to synchronous synchronizers and particularly a technique which involves level shifting of a metastable voltage either within a synchronizer stage or between synchronizer stages. In a particular implementation of the invention, this level shifting is achieved by altering the relative proportions of at least one complementary pair of devices in a synchronizer or inserting diodes in order to shift the level of a metastable voltage outside the range of a fatal voltage window possessed or exhibited by an adjacent or following part or stage of the synchronizer. By this means, although the occurrence of a metastable condition cannot be avoided, the likelihood of propagation of the metastable condition throughout the synchronizer may be very significantly reduced.
