ABSTRACT:
Clock signals of the same phase are formed even when signal delays occur in clock signals transmitted on a clock line. In a clock synchronizing circuit which synchronizes circuit elements using clock signals taken from a common clock line, the clock line is bent midway into a pair of clock lines, and a center phase signal generating means generates a clock signal having a phase which is in the center of two clock signals of differing phase obtained from arbitrary points on the pair of clock lines which are at equal distances from the point at which the clock line is bent over. By using pairs of clock signals of differing phases taken at equal distances from the bend over point, three clock signals all having equal phase are obtained.
