Abstract:This paper proposes wide-range and fast locking all-digital delay-locked loop (WRADDLL) circuit with one cycle dynamic synchronizing. The WRADDLL not only synchronizes the input and output clocks in five clock cycles but maintains one cycle dynamic locking. The WRADDLL reduces the clock skew between the input and output clocks with three innovative techniques. First, by improving the mirror control circuit, the WRADDLL operates correctly with a flexible duty cycle clock signal.Second, the WRADDLL works precise… Show more
