Skew-reduction circuit

摘要

A circuit includes a first phase-adjustment circuit (11) adjusting phases of rising edges and falling edges of an original signal, and a phase-delay circuit (12) receiving a phase-adjusted signal from said first phase-adjustment circuit (11) and generating a delay signal by delaying said phase-adjusted signal by a predetermined phase amount. The circuit further includes a phase-comparison circuit (13) comparing phases of edges between said phase-adjusted signal and said delay signal so as to control said first phase-adjustment circuit (11) such that said phases of edges satisfy a predetermined phase relation. <IMAGE>
