Digital duty cycle corrector
A method for adjusting the relative phases of two signals includes receiving first and second signals, which may, for example, be derived from a differential clock signal. A duty cycle error between the first signal and the second signal is detected by comparing a phase component of the first signal with a phase component of the second signal. This duty cycle error can then be corrected by delaying the second signal by an amount based upon a result derived from the comparing.
