The clock generator (110 and120 ) which offers

摘要

PROBLEM TO BE SOLVED: To perform adjustment so that phase of a clock of a certain region of an integrated circuit becomes the same phase as that of a clock of another region.;SOLUTION: In a method and a device which generate a quadrature clock, a quadrature clock generating device contains a clock generater which provides a double clock which has a double frequency of that of a received reference clock. A frequency divider circuit is combined so that an alignment signal may be offered which has a frequency of the half of the double clock. Following the alignment signal, a first clock and a second clock are recovered from the double clock by a recovery circuit. The first clock and the second clock have a phase difference of substantially 90°.;COPYRIGHT: (C)2005,JPO&NCIPI
