ABSTRACT:
A duty ratio-guaranteed reference clock signal and a duty ratio-unguaranteed drive clock signal serve as input to a clock signal waveform-correcting system in accordance with this invention. The system thereafter puts out a post-correction drive clock signal that is duty ratio-guaranteed. The system has a phase comparator and a switch circuit. The phase comparator puts out a HIGH signal as long as the reference clock signal and the drive clock signal disagree in logical level. The switch circuit transmits an inverted signal as a result of inverting the drive clock signal, to an output signal of a first buffer to which the drive clock signal is applied. A second buffer takes in the output signal and puts out a post-correction drive clock signal.
