Abstract

A clock signal distributing system supplies clock signals exhibiting extremely matched phases as a standing wave without employing extra signals such as a reference signal and the like other than clock signal itself. The system compensates for a phase lag in clock signal sand attenuation in signal amplitude. As a result, clock signals exhibiting extremely matched phases are supplied up to the places to be distributed at the respective terminals without requiring equal-length wiring on, for example, a semiconductor chip. The clock signal distributing system is composed of an electromagnetic transmission path line which transmits periodic clock signals as a standing wave, an amplifier, and a phase advancing unit which advances phases of the periodic clock signals wherein a phase lag in transmission of clock signals and a phase lag in amplitude of the amplifier are corrected in the phase advancing direction by the phase advancing unit.
