Abstract
PURPOSE: To synchronize the asynchronous signal having the signal width shorter than the internal clock period, by taking the logical product between the output signal of the internally synchronized flip flop and the signal delaying the output signal.
CONSTITUTION: When asynchronous input signal 100 is 1, the latch circuit 1 is set to 1 and the internally synchronized FF2 is set to 1 with the leading of the clock signal 106. At this time, if the time in which the signal 101 is 1 is within the preset time of FF2, FF2 is not surely set to 1 and 1 for slight time as unstable output. Further, the signal 102 is delayed with the delay circuit 3 for required time to stabilize the signal 102. Next, the signals 102 and 103 are inputted to the NAND circuit 4, resetting the latch circuit 1, and the signals 102 and 103 are wave-shaped via the AND circuit 5, causing the internal synchronizing signal 105 where transient unstable signal is removed. Accordingly, one type of clock signal only is used and the internal synchronizing signal is produced with minimum delay time.
