US Patent 7138850 High-gain synchronizer circuitry and methods

High-gain synchronizer circuitry and methods are provided that reduce the meta-stable resolve time of a synchronizer circuit. The high-gain synchronizer is made up of high-gain latch circuits. The high-gain latch circuits are made up of a series of inverters that at least initially increase in size and that are connected in a closed loop. In accordance with the invention, the time that the high-gain synchronizer remains in the meta-stable state is minimized through the use of the high-gain latch circuits.
