Abstract
Systems and methods for synchronizing a system clock signal with a reference clock signal having a reduced phased offset to improve operating speeds of integrated circuits. This is accomplished by generating delayed system and reference clock signals by using the system and reference clock signals. The generated delayed clock signals are then monitored to determine the arrival of the raising and falling edges of the delayed clock signals. The system clock signal is then compensated based on the determination of the arrival of the delayed clock signals to substantially synchronize the system clock signal with respect to the reference clock signal.
