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.

Abstract: A voltage-controlled oscillator comprises a plurality of delay circuits connected in a ring configuration. Each of the delay circuits comprises a current source and a differential pair of inverting circuits each supplied with current from the current source. Each of the differential pair of inverting circuits consists of a P-type MOS transistor and an N-type MOS transistor having a drain connected to the drain of the P-type MOS transistor. When a control voltage equal to or higher than the threshold voltage of each N-type MOS transistor is applied to the gate thereof, the voltage at the drain of each P-type MOS transistor oscillates at a frequency corresponding to the control voltage, since each N-type MOS transistor exhibits a linear current characteristic with respect to the control voltage.
