Abstract:
1. A circuit comprising: a skew circuit configured to receive an input signal and provide a deskew input signal, wherein the skew circuit asymmetrically delays rising and falling edges of the input signal to produce the deskew input signal, such that the deskew input signal has a first edge delayed from a second edge of the input signal by a first delay and a third edge delayed from a fourth edge of the input signal by a second delay that is different than the first delay; and a deskew circuit configured to receive the deskew input signal, wherein the deskew circuit asymmetrically delays rising and falling edges of the deskew input signal to provide an output signal having a first deskewed edge delayed from the first edge by a third delay and a second deskewed edge delayed from the third edge by a fourth delay, wherein the difference between the fourth delay and the third delay is substantially equal to the difference between the first delay and the second delay.
