ABSTRACT:
LC resonant voltage control oscillators are adopted as voltage control oscillators for the purpose of providing a clock generating and distributing apparatus that can generate and distribute a clock signal of high precision even in a high-frequency region of several giga hertz or higher, and of providing a distributive VCO-type clock generating and distributing apparatus in which voltage control oscillators oscillate in the same phase, and which can generate a clock signal of a desired frequency and distributes a high-frequency clock signal to each part within a chip more stably even in a high-frequency region reaching 20 GHz. Furthermore, an inductor component of a wire connecting the oscillation nodes of the oscillators is made relatively small, or the LC resonant oscillators are oscillated in synchronization by using injection locking, whereby the LC resonant voltage control oscillators stably oscillate in the same phase.
